He was a local FBI boss, not THE head of the FBI, and he is regarded by many as a disinfo shill. He has been a promoter of just about every bogus theory one can come up with: reptilians, FEMA internment camps, a United Nations army taking over the United States, "pineapple bombs" at Oklahoma, no-planes on 9/11. Gunderson's goal was actually to discredit conspiracy research by introducing fake evidence and pushing fake claims, "poisoning the well," giving talks to groups of conspiracy researches to get them to adopt bad evidence and false "tinfoil hat" versions of their theories (e.g. "no plane at the Pentagon"), in order to discredit the true general claims (e.g. 9/11 = inside job) with the general public. Basic "black propaganda." He promoted the McMartin Preschool case as an example of an elite pedophile ring. The McMartin case is a well-known case of false allegations.
