A vous lire, les Américains n'auraient pas assez d'imagination pour les coups tordus et autres??? C'est vrai, ils n'ont pas vécu chez eux les expériences que vous décrivez. Mais ils ne se sont pas privé d'intervenir et de manipuler partout dans le monde maintenant et depuis toujours et justement pour provoquer des climats bien particuliers dans certains pays.
Ou vous aurais-je mal lu?
Par contre, je suis assez d'accord avec votre conclusion dont la première des causes est l'incompétence et la faillite du système policier de l'époque.
Cela dit, ils ont maintenant eu droit à une autre bande terroriste!

Roy Hazelwood


From Wikipedia, the free encyclopedia


Jump to: navigation, search










Robert Roy Hazelwood (born March 4, 1938) is a former FBI profiler of sex crimes and is generally regarded as the pioneer of profiling sexual predators. He worked for much of his career for the FBI, retiring in the mid-1990s.

[edit] Early life

Roy Hazelwood was born in Pocatello, Idaho. When he was an infant, his biological father, Myrle Reddick, kidnapped him and travelled around with him for six months before returning the boy to his paternal grandparents; father and son never saw each other again.[1] He was raised by his mother and stepfather in Spring Branch, Texas, and attended Sam Houston State University.

He served a tour in Vietnam, which he completed in 1968 as a Major. He followed his tour with a forensic medicine fellowship with the Armed Forces Institute of Pathology (AFIP) and a stint with the CID as an instructor.

He joined the FBI in 1971.

[edit] Career

In 1980, he developed the distinction between "organized" and "disorganized" murderers, a concept that is still used by law enforcement to help in the apprehension of criminals. He also defined the six categories of rapists: power-reassurance, power assertive, anger retaliatory, anger excitation, opportunistic and gang. Of the six, anger excitation is by far the most dangerous and the hardest to capture.

Hazelwood has also offered the theory that there is no cure for pedophilia or sexual sadists. He has conducted numerous studies involving sex crimes, including cases of autoerotic asphyxiation. He has done numerous studies involving the willing victims of sexual sadists (wives and girlfriends) and how sexual sadists appear in everyday life. In his career he found equivocal death crime as the most dubious and complex investigation to overcome.

Hazelwood, now retired from the FBI, is an active member of the Academy Group,[2] an organization of former FBI agents and law enforcement officers. He continues to work closely with the FBI and other government agencies in an effort to track down sexually-oriented murderers. Hazelwood has also co-authored two books with Stephen Michaud: The Evil That Men Do and Dark Dreams.

Hazelwood now gives lectures across North America about sexual sadism and autoerotic fatalities. His presentation is also heavily focused on Dennis Rader, the "B.T.K." serial killer of Wichita.

[edit] Personal life

Hazelwood, a devout Presbyterian, is married with three grown children.

Offender profiling

Offender profiling, also known as criminal profiling, is a behavioral and investigative tool that is intended to help investigators to accurately predict and profile the characteristics of unknown criminal subjects or offenders.[1] Offender profiling is also known as criminal profiling, criminal personality profiling, criminological profiling, behavioral profiling or criminal investigative analysis. Geographic profiling is another method to profile an offender. Television shows such as Law & Order: Criminal Intent, Profiler in the 1990s, the 2005 television series Criminal Minds, the 2011 television series Criminal Minds: Suspect Behavior, and the 1991 film The Silence of the Lambs have lent many names to what the FBI calls "criminal investigative analysis."

Holmes and Holmes (2008) outline the three main goals of criminal profiling:
The first is to provide law enforcement with a social and psychological assessment of the offender;
The second goal is to provide law enforcement with a "psychological evaluation of belongings found in the possession of the offender" (p. 10);
The third goal is to give suggestions and strategies for the interviewing process.[2]

In modern criminology, offender profiling is generally considered the "third wave" of investigative science:
the first wave was the study of clues, pioneered by Scotland Yard in the 19th century;
the second wave was the study of crime itself (frequency studies and the like);
this third wave is the study of the psyche of the criminal.

[edit] Definitions

Offender profiling is a method of identifying the perpetrator of a crime based on an analysis of the nature of the offense and the manner in which it was committed. Various aspects of the criminal's personality makeup are determined from his or her choices before, during, and after the crime.[3] This information is combined with other relevant details and physical evidence, and then compared with the characteristics of known personality types and mental abnormalities to develop a practical working description of the offender.

Psychological profiling may be described as a method of suspect identification which seeks to identify a person's mental, emotional, and personality characteristics (as manifested in things done or left at the crime scene).[4] This was used in the investigation of the serial murders committed by Ted Bundy. Dr. Richard B. Jarvis, a psychiatrist with expertise on the criminal mind, predicted the age range of Bundy, his sexual psychopathy, and his above average intellect.[5]

A further, more detailed example of how psychological profiling may be performed is the investigation of Gary Leon Ridgway, also known as the Green River Killer. This case also demonstrates the potential for incorrect predictions. John E. Douglas, an investigator who worked for the FBI, provided a twelve-page profile, which stated the suspect was:
Probably a white male who had a dysfunctional relationship with women.
Organized since he tried to hide the bodies and appeared to spend some time at the river
Cunning in using rocks to weigh the victims down in the water to conceal them.
Very mobile with a vehicle.
Going to kill again.
Like other serial killers, he would be prone to contacting police wanting to help in the investigations.[6]

However, the profile created for Ridgway also revealed characteristics that did not apply to him, such as being an outdoorsman and being incapable of closeness to other people.[7] Ridgway was not an outdoorsman, but frequented the Green River with one of his wives, and also had a very close relationship with his last wife, which contradicted the point in the profile of being incapable of closeness.

One type of criminal profiling is referred to as linkage analysis. Gerard N. Labuschagne (2006) defines linkage analysis as "a form of behavioral analysis that is used to determine the possibility of a series of crimes as having been committed by one offender."[8] Gathering many aspects of the offender’s crime pattern such as modus operandi, ritual or fantasy-based behaviors exhibited, and the signature of the offender help to establish a basis for a linkage analysis. An offender’s modus operandi is his or her habits or tendencies during the killing of the victim. An offender’s signature is the unique similarities in each of his or her kills. Mainly, linkage analysis is used when physical evidence, such as DNA, cannot be collected.

Labuschagne states that in gathering and incorporating these aspects of the offender’s crime pattern, investigators must engage in five assessment procedures: (1) obtaining data from multiple sources; (2) reviewing the data and identifying significant features of each crime across the series; (3) classifying the significant features as either MO and/or ritualistic; (4) comparing the combination of MO and ritual/fantasy-based features across the series to determine if a signature exists; and (5) compiling a written report highlighting the findings.[8]

[edit] History

The origins of profiling can be traced back to as early as the Middle Ages, with the inquisitors trying to "profile" heretics. Jacob Fries, Cesare Lombroso, Alphonse Bertillon, Hans Gross and several others realized the potential[clarification needed] of profiling in the 19th century although their research is generally considered to be prejudiced, reflecting the biases of their time.[citation needed] A version of profiling is thought to have been used in the 1940s, when investigations relied on mental health professionals to create a profile of an offender in order to aid the police investigation.[9] Soon after, as discussed below, James Brussel was called upon to analyze the information on the Mad Bomber in New York City, and he created an accurate profile of the offender. This caught the attention of the FBI, who then worked to develop a technique for profiling, based on the process used by Brussel.

[edit] Notable profilers

[edit] Thomas Bond

During the 1880s, Thomas Bond, a medical doctor, tried to profile the personality of Jack the Ripper. Bond, a police surgeon, assisted in the autopsy of Mary Kelly. In his notes, dated November 10, 1888, he mentioned the sexual nature of the murders coupled with elements of apparent misogyny and rage. Dr. Bond also tried to reconstruct the murder and interpret the behavior pattern of the offender: soon he came up with a profile or signature personality traits of the offender to assist police investigation. The profile said that five murders of seven in the area at the time the report was written had been committed by one person alone who was physically strong, composed, and daring. The unknown offender would be quiet and harmless in appearance, possibly middle-aged, and neatly attired, probably wearing a cloak to hide the bloody effects of his attacks out in the open. He would be a loner, without a real occupation, eccentric, and mentally unstable. He might even suffer from a condition called Satyriasis, a sexual deviancy that is today referred to as hypersexuality or promiscuity. Bond also mentioned that he believed the offender had no anatomical knowledge and could not be a surgeon or butcher. Moreover, Dr. Bond later concluded that the same offender was responsible for the murder of Alice McKenzie.

[edit] Walter C. Langer

In 1943, William J. Donovan, chief of the US Office of Strategic Services (OSS), asked Dr. Walter C. Langer, a psychoanalyst based in Boston, to develop a "profile" of Adolf Hitler. What the OSS wanted was a behavioral and psychological analysis for the construction of strategic plans, given various options.

Dr. Langer used speeches, Hitler's book Mein Kampf, interviews with people who had known Hitler, and some four hundred published works to complete his wartime report, which was eventually declassified by OSS and published by Langer (along with certain collateral material) as The Mind of Adolf Hitler in 1972. This work contains a profile of possible behavioral traits of Hitler, and his possible reactions to the idea of Germany losing World War II. Dr. Langer’s profile noted that Hitler was meticulous, conventional, and prudish about his appearance and body. He was robust and viewed himself as a standard-bearer and trendsetter. He had manic phases, yet took little exercise. Due to a lack of evidence, Langer believed that Hitler was in reasonably good health,[10] so it was unlikely he would die from natural causes, but he was deteriorating mentally. He would not try to escape to a neutral country, nor would he (in Langer's opinion) allow himself to be captured by the Allies. Hitler always walked diagonally from one corner to another when crossing a room, and he whistled a marching tune. He feared syphilis and germs.

Langer's profile also pointed out Hitler's oedipal complex, with the effect being the need to prove his manhood to his mother, and his masochistic coprolagnia and urolagnia. He detested the learned and the privileged, but enjoyed classical music, vaudeville, and Richard Wagner's opera. He showed strong streaks of sadism and liked circus acts that were risky and dangerous. He tended to speak in long monologues rather than have conversations. He had difficulty establishing close relationships with anyone. Since he appeared to be delusional, it was possible that his psychological structures would collapse in the face of imminent defeat. The most likely scenario was that he would commit suicide, although there was a possibility that he would order a henchman to perform euthanasia.

[edit] James A. Brussel

Between 1940 and 1956, a serial bomber terrorized New York City by planting bombs in public places including movie theaters, phone booths, Radio City Music Hall, Grand Central Terminal, and Pennsylvania Station. In 1956, the frustrated police requested a profile from Greenwich Village psychiatrist James A. Brussel, who was New York State's assistant commissioner of mental hygiene. Dr. Brussel studied photographs of the crime scenes and analyzed the so called "mad bomber’s" mail to the press. Soon he came up with a detailed description of the offender. In his profile, Dr. Brussel suggested that the unknown offender would be a heavy middle-aged man who was unmarried, but perhaps living with a sibling. Moreover, the offender would be a skilled mechanic from Connecticut, who was a Roman Catholic immigrant and, while having an obsessional love for his mother, would harbour a hatred for his father. Brussel noted that the offender had a personal vendetta against Consolidated Edison, the city’s power company; the first bomb targeted its 67th Street headquarters. Dr. Brussel also mentioned to the police that, upon the offender's discovery, the "chances are he will be wearing a double-breasted suit. Buttoned."

From his profile, it was obvious to the police that the mysterious bomber would be a disgruntled current or unhappy former employee of Con Ed. The profile helped police to track down George Metesky in Waterbury, Connecticut; he had worked for Con Ed in the 1930s. He was arrested in January 1957 and confessed immediately. The police found Brussel’s profile most accurate when they met the heavy, single, Catholic, and foreign-born Metesky. When the police told him to get dressed, he went to his bedroom and returned wearing a double-breasted suit, fully buttoned, just as Dr. Brussel had predicted. However, Malcolm Gladwell has written that offender profiling is not a science at all, but is couched in such ambiguous language that it can support almost any interpretation; and about Brussel says:[11]


Brussel did not really understand the mind of the Mad Bomber. He seems to have understood only that, if you make a great number of predictions, the ones that were wrong will soon be forgotten, and the ones that turn out to be true will make you famous. The Hedunit is not a triumph of forensic analysis. It’s a party trick.

Dr. Brussel assisted New York City police from 1957 to 1972 and profiled many crimes, including murder. Dr. Brussel also worked with other investigative agencies. Brussel’s profile led the Boston Police to the apprehension of Albert DeSalvo, the notorious serial sex murderer known as the Boston Strangler. The media dubbed Dr. Brussel as "Sherlock Holmes of the Couch".[12]

[edit] Howard Teten

Howard D. Teten, a veteran police officer from California, joined the FBI in 1962. He was appointed as an instructor in applied criminology at the old National Police Academy in Washington, D.C. Teten was greatly interested in the application of offender profiling, and had included some of the ideas in his applied criminology course. He met Dr. Brussel and exchanged investigative ideas and psychological strategies in profiling crimes. Although Teten disagreed with Dr. Brussel's Freudian interpretations, he accepted other tenets of his investigative analysis.

In 1972 the FBI’s Behavioral Science Unit at Quantico was formed, with Teten joining FBI Instructor Patrick J. Mullany's team. Teten and Mullany designed a method for analyzing unknown offenders in unsolved cases. The idea was to look at the behavioral manifestations at a crime scene for evidence of mental disorders and other personality traits, thus aiding the detectives' deductive reasoning. Their ideas on offender profiling were tested when a seven-year-old girl was abducted from a Rocky Mountains campsite in Montana in June 1973. The girl was abducted from a tent in the early hours; the offender overpowered her before she could alert her parents, who were sleeping nearby. When an intensive search for the missing child failed, the case was referred to the FBI.

Teten, Mullany and Col. Robert K. Ressler employed their criminal investigative analysis technique to track down the unknown offender. Their profile declared that the abductor was most likely a young, white, male, homicidal Peeping Tom; a sex killer who mutilates his victim after death, who sometimes takes body parts as souvenirs. Later, the profile led to the arrest of David Meirhofer, a local 23-year-old single man who was also a suspect in another murder case. The search of his house unearthed "souvenirs"—body parts taken from both victims. Meirhofer was the first serial killer to be caught with the aid of the FBI's new investigative technique, called offender profiling or criminal investigative analysis. A decade later, the technique became a more sophisticated and systematic profiling tool known as the Criminal Investigative Analysis Program (CIAP).

[edit] Richard Walter and Bob Keppel

In 1974, homicide detective Robert D. Keppel used new methods of psychological profiling to investigate notorious serial killers Ted Bundy and the Green River Killer. He combined his field expertise with criminal psychologist Richard Walter. As a psychologist in Michigan's notorious prison system, Walter had interviewed over two thousand murderers, sex-offenders and serial killers. Walter began to see common threads among offenders and was able to group all killings and sex crimes into four distinct "subtypes": power-assertive, power-reassurance, anger-retaliatory, and anger-excitation or sadism. He was the first to develop a matrix using suspect pre-crime, crime and post-crime behaviors as a tool for investigation. Walter later co-founded the Vidocq society, an exclusive organization of forensic professionals who solve cold cases for law enforcement agencies, worldwide. Together, Keppel and Walter created the HITS (Hunter Integrated Telemetry System) database, which lists characteristics of violent crimes so that common threads can be investigated. They also published a leading scholarly article for the FBI and violent crime investigators all over the world: "Profiling Killers: A Revised Classification Model for Understanding Sexual Murder".

[edit] John Douglas and Robert Ressler

In 1978, after Howard Teten left the Behavioral Science Unit, John Douglas and Robert Ressler became pillars of offender profiling in the FBI. They spent much time studying convicted sex murderers and interviewing them, creating organized and disorganized typology, which is still in use today.[13] Ressler was also responsible for the founding of the National Center for Analysis of Violent Crime (NCAVC) and at least partially responsible for the establishment of VICAP. Their studies provide more information on the behavioral patterns, traits and characteristics of criminals which can then be added to the offender profiling program.

[edit] David Canter

In 1986, police forces across the south of England were struggling to find the Railway Rapist who was then renamed the Railway Killer after murdering a victim for the first time. Dr. David Canter, a psychologist and criminologist then from Surrey University, was invited to compose British crime's first offender profile. When John Duffy was later arrested, charged and convicted, it turned out 13 of Canter's 17 proclamations about the perpetrator were accurate. Profiling became commonplace in large-scale police searches afterwards.

[edit] Phases of profiling

According to Gregg O. McCrary, the basic premise is that behavior reflects personality. In a homicide case, for example, FBI profilers try to collect the personality of the offender through questions about his or her behavior at four phases:
1.Antecedent: What fantasy or plan, or both, did the murderer have in place before the act? What triggered the murderer to act some days and not others?
2.Method and manner: What type of victim or victims did the murderer select? What was the method and manner of murder: shooting, stabbing, strangulation or something else?
3.Body disposal: Did the murder and body disposal take place all at one scene, or multiple scenes?
4.Post-offense behavior: Is the murderer trying to inject himself into the investigation by reacting to media reports or contacting investigators?

A sexual crime is analyzed in much the same way (bearing in mind that homicide is sometimes a sexual crime), with the additional information that comes from a living victim. Professor David Canter is the pioneer of scientific offender profiling, developing the discipline of Investigative Psychology as a response to his dissatisfaction with the scientific bases for this activity. The IAIP of which Canter is President now seeks to set professional guidelines for practice and research in this area.

Another phase of criminal profiling (crime scene investigation) is case linkage. According to Brent E. Turvey, case linkage or linking analysis refers to the process of determining whether or not there are discrete connections between two or more previously unrelated cases through crime scene analysis.[14] It involves establishing and comparing the physical evidence, victimology, crime scene characteristics, modus operandi (MO)-organized or disorganized typologies-, and signature behaviors between each of the cases under review. It has two purposes:
1.To assist law enforcement with the application of its finite resources by helping to establish where to apply investigative efforts and
2.To assist the court in determining whether or not there is sufficient behavioral evidence to suggest a common scheme or plan in order to address forensic issues, such as whether similar crimes may be tried together or whether other crimes may be brought in as evidence.

With respect to behavioral evidence, case linkage efforts have most typically hinged on three concepts:
1.MO, modus operandi
2.Signature
3.victimology

[edit] Problems with Offender Profiling

There are major problems with offender profiling that have been identified.

Incorrect information from profiling can lead to false positives or false negatives. Investigators may find a suspect who appears to fit an incorrect profile and ignore or stop investigating other leads. For example, Richard Jewell was wrongly investigated (and attacked in the media) following the Centennial Olympic Park bombing in Atlanta. This not only caused great distress to Jewell, but delayed identifying the true culprit, Eric Robert Rudolph. This was a false positive: the profile identified Jewell as the offender when in fact he was not. The opposite of the false positive is the false negative: the profile yields incorrect information which would cause investigators to ignore a suspect who is actually guilty. For example, in the Beltway sniper attacks, the offender profile indicated that the killer was probably a white male in his thirties from the DC area acting alone— in fact, the crimes were perpetrated by two black males, one of whom was 41 and the other 17 years old, from the west coast of the U.S.[15]

The Peggy Hettrick murder case is controversial because it is the only documented case of an individual having been convicted due to a reversed engineered false profile and the erroneous testimony of the psychologist who developed the profile. In 1999, a jury convicted Timothy Masters of the 1987 killing of Peggy Hettrick. Masters spent over 9 years in a Colorado prison before his release on January 22, 2008. Timothy Masters was arrested and convicted of sexual murder based on the testimony of a forensic psychologist while the opinion of a Robert R. "Roy" Hazelwood, a retired FBI criminal investigative analyst was ignored. The forensic psychologist developed a psychological profile of a killer using narrative and drawings made by Masters to conclude that Masters’ supposed fantasy was the motive and behavioral preparation for the sexual murder, regardless of the fact that the forensic psychologist knew that there was no direct or physical evidence linking Masters to the crime. The cautionary lesson in the Masters case is what happens when forensic psychologists advance opinions about criminal matters based on the extrapolation of academic research on psychological concepts involving sexual homicide cases and reject the opinions of professional criminal profilers who incorporate law enforcement analysis coupled with criminal evidentiary considerations into their work.[16]

Some experts in criminal psychology such as Brent Turvey, as quoted by journalist Malcolm Gladwell in The New Yorker[17] have questioned its scientific validity. Many profilers and FBI agents are not psychologists, and some researchers who looked at their work found methodological flaws.

Three psychologists from the Universities of Liverpool and Hull are questioning the basic presumption that you can draw conclusions about a person from a single instance of behaviour under such special circumstances. "The notion that particular configurations of demographic features can be predicted from an assessment of particular configurations of specific behaviors occurring in short-term, highly traumatic situations seems an overly ambitious and unlikely possibility. Thus, until such inferential processes can be reliably verified, such claims should be treated with great caution in investigations and should be entirely excluded from consideration in court."[18]

Active profiling as allowed by the Department of Justice includes covert alteration of the environment to observe the responses of a suspect. This can be used to check whether the suspect's behavior fits the profile, but risks being labeled as police harassment or entrapment.[citation needed]

Popular use of the term criminal profiler has led to the proliferation of many self-described profilers offering their purported expert opinions on cable news shows in response to incidents capturing national attention in the United States. Such individuals usually have degrees in criminal justice or psychology but lack any law enforcement experience, or vice versa.[citation needed]

"James Brussel didn’t really see the Mad Bomber in that pile of pictures and photostats, then. That was an illusion. As the literary scholar Donald Foster pointed out in his 2000 book "Author Unknown," Brussel cleaned up his predictions for his memoirs. He actually told the police to look for the bomber in White Plains, sending the N.Y.P.D.’s bomb unit on a wild goose chase in Westchester County, sifting through local records. Brussel also told the police to look for a man with a facial scar, which Metesky didn’t have. He told them to look for a man with a night job, and Metesky had been largely unemployed since leaving Con Edison in 1931."

13.^ "Organized crimes are premeditated and carefully planned. These characteristics suggest that the perpetrator may display psychopathic tendencies, because this type of person remains in touch with reality, under stress. Little evidence is found at the scenes of this type of offender, they are antisocial but understand right from wrong, but have a shallow affect; thus not showing remorse. Disorganized crimes are unplanned, impulsive acts of violence. This individual uses weapons available at the scene, like blunt force objects for example. They leave many forms of evidence, like fingerprints and blood. Being out of touch with reality and social norms, these offenders are clinically psychotic."

Le peu de littérature en français sur le sujet en dit long sur la prévention à l'égard de la méthode qui doit contrarier les enquêteurs restés sur les bonnes vielles méthodes qui...n'ont pas fait leurs preuves pour les TBW...

A vous lire, les Américains n'auraient pas assez d'imagination pour les coups tordus et autres??? C'est vrai, ils n'ont pas vécu chez eux les expériences que vous décrivez. Mais ils ne se sont pas privé d'intervenir et de manipuler partout dans le monde maintenant et depuis toujours et justement pour provoquer des climats bien particuliers dans certains pays.
Le réseau "Echelon" désigne un système mondial d'interception global des communications élaboré par les États-Unis, le Royaume-Uni, le Canada, l’Australie et la Nouvelle-Zélande dans le cadre du traité "UKUSA".Ce réseau est resté classé "secret défense" et donc totalement inconnu du grand public pendant plus de 40 ans jusqu'à ce qu’un journaliste écossais, Duncan Campbell, dévoile le projet "Echelon". ce qui explique qu'il a muté pour devenir "Prism". On sait aussi, suite à "l'affaire Swordsmen", qu'il n'a pas pour autan acquit la capacité de neutraliser son "gêne tueur" qui était prévus pour le neutraliser dans l'éventualité où il aurait l'idée saugrenue de vouloir se retourner contre ceux qui l'on créé cheers

Et puisqu'il est à l'écoute, je lui conseillerais "aussi" de retirer cette idée de sa tête sans quoi il sait ce qui lui pend au nez

Citation :
In modern criminology, offender profiling is generally considered the "third wave" of investigative science:
the first wave was the study of clues, pioneered by Scotland Yard in the 19th century;
the second wave was the study of crime itself (frequency studies and the like);
this third wave is the study of the psyche of the criminal.



Scotland yard a du foutre 400 agents dehors car trop proche du milieu criminel pour restructurer après l'attaque du train et la fuite d'un des gangsters du prison

donc toutes ces théories de profilage....

et en belgique "la chasse au taupes" après trente ans

Comment peut-on, dès lors, briller dans une analyse, quand le facteur "milieu" est totalement étranger ??
C'est a ca que servent les agents infiltrés des services secrets.
Si j'en crois les déclarations de l'ancien Président francais Francois Mitterand la CIA a mené des opérations illégales et financières via la banque Rothschild. Selon d'autres sources la CIA aurait même infiltré le Gouvernement francais et même appuyé de l’intérieur le courant proeuropéen

En tant que "enfant de la grande muette" c'était même un de nos passe-temps de faire la chasse aux espions soviétiques qui opéraient le plus souvent sous couverture "culturelle" comme Vladimir Poutine en poste à la "Maison de l'amitié germano-soviétique" de Dresde. Laughing

Beersel 2: Fredo (beetgenomen)

d'ailleurs où j'ai lu que FREDO a essayé de toucher le prime TBW juste avant d'être mis à la porte de la Pj en decembre 1983 pour avoir tenu un caberdouche etant en fonction à la police jud.
