I listened to Rex's comments on Lee Harvey Oswald's firing position and the (alleged) difficulty of the shots he made on the Kennedy motorcade. I could not agree with Rex more. The range to target looked very close. It seems like a person with even moderate skill and possibly a bit of luck coukd have pulled thise shots off.
I also agree with Rex that Commie-Oswald likely had accomplices. It is just too suspicious to me that immediately after killing the President of the United States - a guy could get close enough to Oswald to assasinate him with a snub nosed .38 and forever silence him.
