Shooting JFK isn't the problem, It's straight in and through, nicking the spinal column on the way.
If you want to "debunk the nagic bullet", you have to come up with an alternative theory on how Governor Connolly's wounds were caused.
I'm not interested in the magic bullet theory, I merely said it has always been the crowd favorite, or put another way, the most popular explanation.
It's the head shot, the kill shot, that has always interested me.
