I was just perusing the eponymous Wikipedia article when I read about Frank Olson. I had heard the story before, but it was a nice refresher. Basically, he was a scientist working for the CIA who was given a wicked dose of LSD, which caused him to hallucinate, go crazy, and then throw himself from a building. Or he was murdered. The CIA was quiet about it because they were testing on the rest of the populace. This is why you don't trust your government and you turn to people like Jesse Ventura for your news.
