SMG--
The JFKA CT is nor proven, but neither is the LNT.
Remember, the first official investigation (WC) said LHO acted alone (and let's admit, under heavy pressure from LBJ), but the second official investigation (HSCA) concluded there was likely was a conspiracy.
And the HSCA had a lot of smart and skeptical guys on it, and they did not buy most CT's (the BYP were fake, LHP never owned the rifle, etc.), and the HSCA left LHO in place as a shooter.
In general, I think the second official investigation got it right. There was a JFKAC.
Others disagree. That is what a forum is for.
