I was just thinking about this earlier, as to whether CCW would have any impact on school shootings. To the best of my ability to get into the head of a shooter, I came to this conclusion:
-- I don't expect to get out alive in the first place (or care).
-- I probably have several specific targets (bullies/teachers/etc) and general malaise towards everyone else
-- I enjoy the thought to going in there are shooting people up
Basically, I'm thinking of 3 situations:
1) if I only wanted to target individuals, I'd go to their homes.
2) If I wanted to target individuals and a group, I'd do it at school.
3) If I only wanted to target the faceless masses of my peers, I'd do it at school.
So, the impact of thinking that there was a chance that there were people armed, I'd move a lot faster to the "shoot randomly into the crowd phase" to accomplish whatever notoriety goal I was trying to get. Plus I'd target large groups (lunch room) instead of walking through halls and classrooms.
Would CCW help the situation? To some extent there is a possibility it could limit the damage by providing a faster reaction time than regular authorities could provide. But that is only in situation 2 above. More importantly, it wouldn't exacerbate the situation, so you gotta follow the "allow CCW" path.
PLEASE NOTE: that I have absolutely no idea how these people think. Just trying to make a guess. If anyone CAN comprehend the actions of these individuals, please present yourself to the appropriate authorities.
