Oh god you guys are stupid. Who the hell is gonna take over a school with a knife? The cop on campus will cap the hell out of him. If he has a gun and kills the cop, the -blam!- makes you think you are gonna karate your way to him and brake his bones. I hope it happens to you guys so natural selection takes over and you guys take a .9 to the face. I would hide like all of you would. Stop acting hard and go jerk off
