I was a kid in grade school when both of these events happened.  Yep, we were "taught" about the evil "lone" gunman.  As I grew up and wised up, looking back, none of what they tried to have us believe made any sense.  I am a believer that GHW Bush (head of CIA at the time) was involved along with LBJ.  The "hit" was arranged by them and possibly carried out by mob assassins.  IMO.
