The History Channel had a program on the Jim Jones cult and the mass “suicide” at Jonestown in Guyana.  I didn't really know anything about it except for vague references so it was good to learn about it.  I had no idea that a U.S. Congressman was killed down there when things went down.  I read through the Wikipedia article on Jonestown and saw that there are some conspiracy theories (involving the CIA) that sound really startling (they probably always are) but I don't know if there's any truth to the matter.
