Convicted child molesters? Majority? Proof?
Criminal cases
Although NAMBLA itself has never been prosecuted, there have been a number of prosecutions of alleged NAMBLA members for sexual offences involving children or adolescents.
One cases involved a number of men arrested by the FBI in Los Angeles and San Diego in February 2005. Seven men were charged with planning to travel to Mexico to have sex with boys, the FBI said. An eighth man was charged with distributing child pornography.[4] According to a media report,[4] the FBI believes that at least one of the arrested men
is a member of NAMBLA's national leadership, a second organized the group's national convention last year and a third said he had been a member since the 1980s.
Roy Radow, a self-described pedophile and member of the NAMBLA Steering Committee sometimes described as its chairman or spokesman, was arrested in 1996 for masturbating in front of a 12-year old boy. The trial ended in a hung jury.[26]
John David Smith, a San Francisco man, unwittingly spoke of his crimes to an undercover investigator who had infiltrated NAMBLA. Upon obtaining a warrant, the investigator also found child pornography in Smith's apartment. He was arrested in 1996 and was subsequently convicted of sexually assaulting an 11-year-old boy he was babysitting. Smith's membership in NAMBLA was raised at trial to prove his lascivious intent.[27][28][29]
Paul Shanley, a Catholic priest convicted of abusing children as young as six years old over a period of three decades, allegedly participated in NAMBLA workshops and advocacy, according to contemporaneous accounts of the events obtained by the Boston Globe.[30][31]
Johnathan Tampico was convicted of child molestation in 1989 and paroled in 1992 on condition that he not possess child pornography. After moving without informing authorities of his new address, he was found after a broadcast of America's Most Wanted. He was arrested and convicted on child pornography charges. In his sentencing, the court stated that Tampico was a member of NAMBLA, and that he and others frequently traveled to Thailand to have easy access to young boys. The court cited a number of Polaroid pictures provided by Thai officials depicting Tampico with young Thai boys sitting on his lap as evidence of the latter claim.[32][33]
James C. Parker, a New York man who, according to court records, told the police that he was a member of NAMBLA, was arrested in 2000 and convicted in 2001 of committing sodomy with a young boy.[34]
Alan J. Horowitz, an Orthodox Rabbi and adolescent psychiatrist, pleaded guilty in 1992 of sodomizing three boys ages seven to nine, and molesting one girl, aged 14. He had previously been convicted of molesting two boys in 1983. While in prison he wrote for the NAMBLA newsletter.[35]
This is just a short list. And this of course does not include the number of people that are pedophiles but have not been caught.
