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.
