This certainly is an intriguing subject. Seems that folks are either for the single gunman theory or the conspiracy theory, and are adamant for whichever of the two is their choice. It is amazing how many theories there are to prove either case - all kinds of so-called experts coming out with computer enhancements, or simulations, to prove their view. I really think some of the evidence is hokey, and there really are too many unexplained or unexplainable bits to the story to convince me that it was only Oswald (or evn if it was Oswald) acting alone. I'll bring in a personal experience which I have never, ever seen made reference of anywhere. When I was stationed in Italy, I was doing research on WW II Italian small arms and visited the military museum in Rovereto. The curator of the museum told me that after the assassination, the US sent a team of experts to Italy (I recall him telling me that at least one member was from the FBI; I don't recall what other US agencies may have been involved, but probably Secret Service as well) to work with the Italians to determine if in fact an expert marksman with a 6.5 Carcano could hit a moving target replicating the distance and speed of the assassination. The Italians came up with the best guy they had with the Carcano (no jokes, please - this time I agree with a large part of what Moosekarloff says in his comment, but not that which concerns the killing power of the 6.5mm; it's a good, lethal military cartridge), and neither he nor any of the Americans (apparently, we sent some sharpshooters over as well) could acquire the target with the scope and get off aimed shots in the timeframe that Oswald supposedly did. I just wonder why no one ever mentioned this delegation to Italy in any reports or investigations? I believe the curator of the museum - I don't think he was making it up out of thin air. Anyway, just another mystery surrounding the assassination. I think there was a lot of bungling, and maybe even a coverup, for whatever the reasons. Bottom line: I find it hard to believe that Oswald did it, or did it alone.
