'Gun Free zones' repeadedly only effect the law abiding citeznes. Any law you pass will only effect the law abiding citizens. The only way it effects criminals and psychos is it makes their jobs easier and safer.
Liberty University recently supported concealed carry on campus and really encourages it. Any gunman is probably going to think twice if as soon as he attempts something there's a chance he'll get shot instantly.
I read an article recently that was very powerfull and it said (Here on earth) 'Justice only happens in real time'. I couldn't agree more, also "The only way to stop a bad guy with a gun, is with a good guy with a gun.'
Reffering to the OT, I know several teachers and obviously I know a lot of teens that know even more teachers. Most of them are flaming Liberals that are behind a lot of this gun 'banning' (Big surprise, the government funded teachers union prefers to employ liberals that will vote the liberals in again, 'mind blown'
). I don't know that I would arm every teacher, but I'd definitely allow concealed carry and armed security.
BTW, I'm homeschooled and my father often carries and I'm in a generally well armed house. I'd highly suggest homeschooling to anyone who can, pm me if you have any questions.
Its simply a dangerous world today, just be prepared.
