Sadly this is a prime example of gun control failing, the laws we put in place greatly increase the likelihood of a violent crime in respect to the "Gun Free Zone." If this case alone doesn't show you that no matter what the training, experiences, etc, people can and will still become victims. Criminals target "soft targets" which are people who feel safe, and know they aren't armed. It's our right to defend ourselves, and the governments shouldn't put limits on it. Cops aren't the answer, because even if we had one on every street corner, they still can't deal with everything going on. What is the answer is to stop disarming law-abiding citizens and focus on the criminals with gun.
