Tears from uncle obie? Let's see. I believe that he and the other constitutional violaters would be tearing up because (reportedly) the AR was not used thereby denying them the "assault" weapon angle to use in their pursuit of curbing the 2nd. I say to those that live in the rarified atomosphere that most of these violaters live in, shut up and get behind your armed security detail.
Voluntary carry by indoctrinators (sadly, I refrain from using the term "teacher" any longer) with a couple of weeks training at FrontSight would be a good first step. I'm sure Dr. P would provide such at a reduced fee.
