Jack Ruby was just too convient.[/quote]
No doubt that someone/people didn't want this to go to trial - not that Oswald didn't kill JFK, but that he didn't act alone, as in it wasn't his idea alone. I think that is patently obvious, as otherwise he was just a "nutjob", which doesn't seem to be the case. Nowadays it would be seen as a guy trying to get his 15 minutes of fame on Network TV (this wasn't televised, hence the Zapruder film), or on you tube by a camera phone (didn't exist then), and he did try to get away (hence the killing of Tippett).
Easy to dismiss Ruby as a zealous patriot, who acted on his own - I don't buy that either. Of course this was Texas, so everyone brought guns into Jails with them as a matter of course, right? - lesson learned that maybe screening potential assassins was a good idea in this environment. Having said that, either JR really believed in Omerta (hence why he was tapped), or he gave up a huge payday before he died by not revealing his connections to the crime. So still a quandary either way, which is why it is a mystery 50 years later. That and who really killed Marilyn Monroe (year earlier), is why the Kennedy's remain iconic figures in American lore (since no one normally cares about politicians shortly after they die) to this day. Did Sirhan also act alone? Lots of people wanted the Kennedy's dead, but who would actually arrange for this to happen? Lots of people hate Obama (and other politicians), but he hasn't been assassinated. Why the Kennedy's? Can't believe that these two (Oswald and Sirhan) are the only two "nutjobs" who had motive and opportunity, a little too convenient.
