Bradley Willman (born 1980) is an anti-pedophile activist from Canada who engaged in private investigations using the Internet to expose pedophiles. At one time, he had unfettered access to between 2,000 and 3,000 computers that had been used to visit websites of interest to pedophiles as the result of his use of a Trojan horse. Willman's actions helped put California Superior Court judge Ronald Kline in prison for more than two years in 2007 for possession of child pornography. However, the legality of Willman's use of the Trojan horse was a basis for appeal by the judge. Biography Early life Willman was born in 1980 in Langley, British Columbia, Canada. Private investigator Willman identifies himself as a "private computer cop" and previously used the aliases "Garbie" and "Omnipotent." In the late 1990s, Willman began tracking and investigating people who downloaded child porn from the Internet. At some time before 2000, Willman devised a Trojan horse, a type of computer program, that he used to conduct his investigations. The Trojan horse was posted to websites of interest to pedophiles in a way that it appeared to be a picture-file attached to a message, but was actually a program file. When a visitor to the pedophile website downloaded the file, the visitor unwittingly downloaded the Trojan horse, and would typically be unaware that it was running on his or her computer. Willman had no control over who chose to download the Trojan horse. Once it had been downloaded, Willman could access, search, and retrieve files from the infected computer. Willman stated "My whole intent, after the program started working as I expected it to, was to help kids." Willman estimated that his Trojan Horse gave him access to between 2,000 and 3,000 computers that had been used to visit websites of interest to pedophiles, including those of police officers, military personnel, social workers, priests, and judges. Pre-Kline investigations In March 2000, Willman helped the Royal Canadian Mounted Police with a child molestation case. Some time after August 2000, Willman anonymously provided to a private watchdog group documents related to a Kentucky state investigation of child molestation and production of child pornography. Prior to January 2001, the United States Customs Service contacted Willman to see whether he had discovered any useful information related to a suspected Russian child pornography ring.
