I think the only hope you have to find out the truth about this, will be if you are fortunate enough to have a second generation involved in the cover up and prove that.
Secondly I have derived at the conclusion the reason Rubenstein was going neuro-paranoid and started talking about stuff he was over heard like something about he can't let the Jews get blamed, . . .
that was because his association with Organized Crime and contacts at the cops in Dallas's favorite strip bar made it possible for a leak from the guy who stated that he was a patsy,
and because that patsy, . . Lee Harvey Oswald was still alive and that might be blamed on the cop that had the table turned on him when LHO killed him , . .
and therefore, "Ruby had to kill Oswald, but could not use a, "head shot", because of the danger to others there, so he shot him in the belly, and the rest was left to others during his ride to the hospital and or when he arrived.
Main Motive, as I see it now, BIG oil needed to sell lots of Weapons to Israel, right away, and Texans where starting to look Bad with the Arabs around, and JFK wasn't buying it.
Second generation, . . you don't have to be a genius to figure that out.
I think the second generation are the the ones that murdered Brown, . .
and that might be provable, so you need to start in 2013 and work your way back a half a century.

BTW
If you read that Secretary of Commerce Brown was assassinated by, "Big-Oil",
and promoted Obama to cover it up, . do you think you could you prove it didn't happen?
