The only thing I'd like to add to this discussion is the following : To any and all acolytes of Gerald " The Plagiarist " Posner. While Jack Ruby's presence at Dallas PD HQ on numerous occasions between Oswald's arrest and eventual demise may be explained away as the actions of a distraught, attention seeking hothead working up the nerve and looking for an oppurtunity to do his deed, his knowledge of Oswald's affiliation with the Fair Play For Cuba committee is not so easily explained. FPFC was a very obscure group. Oswald was the sole member of the New Orleans "chapter". The Dallas PD spokesman didn't even know the proper name until Ruby corrected him at the Friday night news conference, so that information couldn't have come from any of Ruby's cop "buddies". Of course all of Ruby's stalking of Oswald also flies in the face of the impulsive, last-second, would've never left Sheba in the car Sunday morning stroll down the ramp to "see if Oswald was still there", but I'm not going to get into that.
