Bors - I was just going to make that same post. Good call and great points.
"Gun Free" doesn't mean a @#$%$ thing to criminals, it just disarms the law abiding citizens who would have at least had a chance to get a few rounds in to that guy before he'd killed 8 people.
Fish in a barrel. Thats what it was like - same goes for the Virginia Tech shootings. I don't carry very often, even though I have a CCW, due to the number of "gun free" areas, where only the criminal will take a gun. Same with college campuses. I can see not having guns in the dorms, obviously, but to be a CCW holder and not be able to walk through campus or carry in class makes campus classrooms an excellent place to walk in and kill 30-50 people with little to no resistance.
