I can’t remember where, but I recently read something on assassinations. They stated that it had long been a mafia trick to recruit “crazy people” to commit assassinations. The theory is that, being crazy, no one will actually pay attention if they say anything–anything at all. I mean, they’re crazy, you know?
This was brought up in the context of Lee Harvey Oswald and the assassination of John F. Kennedy. But given the recent (well relatively recent) number of seriously nut job shooters, I have to wonder if someone has caught onto the trick.
