Seems to me that the modern A-G movement got a good start in November of '63(JFK). It sort of died down a bit after that, but that's where I think it started.
It picked back up in April of '68 (MLK) and really got up a head of steam in June of '68 (RFK).
The everyday gun owner has been paying the price for the whack-job "shooters" ever since.
It's still happening. Everytime one of these morons goes off, the anti gun crowd/government decides it's time to jack around with the lawful gun owners.
You know the rest.
