There's a very disturbing book that I have (I've only partially read it) called “The Last Undercover: The True Story of an FBI Agent's Dangerous Dance with Evil” by Bob Hamer. It's about an FBI agent who infiltrated NAMBLA.
The man is a hero.
How long do you think it's going to be before the popular culture starts to view him as a villain?
I am certain that the day is coming.
