it's been proven through testing that it was one man and it was lee harvey oswald. and why wouldn't one man do this if he had psychological problems. why wouldn't you believe that one man would do something like this just like the hundreds of other ppl who died at the hands of one lone in. it was one man who shot at reagan, it was one man who shot at lincoln, it was one man who shot at john lennon, give me a break what makes this any different. i know our government is corrupt and messed up but ppl need to get real. have you seen elvis lately eating at the mcdonalds?....read a dictionary and learn the definition of religion and spirituality
