I don't consider myself sheltered: I watched the news this morning, and this evening after work, as well as listening to talk radio to and from work. Not a single mention of the anniversary. I think that's pretty sad.
It just boggles my mind that people still think that Lee Harvey Oswald killed him. The first shot may be open to debate, but the final blow is clearly, clearly, CLEARLY delivered from the front! The laws of physics dictate this! I personally believe that he was shot from one of the sewers along the roadway that allowed a clear shot, and could easily fit a man with a rifle.
