My point exactly ... your point about liberals unable to accept the fact a mouse like Oswald (who in many respects was one of them) could kill such an esteemed member of their ranks is a good one.
One other point the conspiracy cool-aid drinkers can't explain away ... the weapon Oswald used to assassinate Kennedy was found hidden in the Book Depository (shortly after the shooting) with Oswald's prints on it, the weapon had been recently fired, and the ballistics matched.
Guilty knowledge was demonstrated too. Else Oswald shot the cop because he didn't like the movie!
