jbee;555038I am sure if there was a Marine with a knife and concealed .45 sitting in the front row said:Best anyone can honestly say with complete certainty is that MAYBE a CCW holder sitting nearby might have stopped the Arizona shooter before he killed X number of people and wounded Y number instead of killing 6 and wounding 19.
Would it have helped? Very possibly. But how is this related to the OP?
I agree with let's enforce the laws on the books and leave legal firearms owners the heck alone.
In the situation where you were legal and now are no longer legal because of a choice you made or you are no longer of sufficient mental capacity, then maybe having a firearm isnt the best thing for you.
