This knife slashing attack in Texas is further evidence that banning guns does not and will not control violence as there is always some lunatic willing to commit horrible acts of violence. I know it's cliche, but guns aren't the problem, whackos are the problem. Again, the attacker takes advantage of a gun-free zone to safely commit his crimes. This wouldn't have happened in a place where a single "good guy" with a CCW were present. Legislators, take notice!
