I guess “gun free” zones don’t work…

A 22-year-old Phoenix man shot three people yesterday. Fortunately, nobody was killed and the three victims were hospitalized with non-life-threatening wounds.
The incident took place at the South Mountain Community College, a “gun free zone”.
When will people wake up and realize that laws, rules, and regulations proclaiming an area to be a “gun free zone” are barely worth the paper they’re printed on?
The only people guaranteed to be at the scene of a violent crime are the perpetrator(s) and the victim(s). Since the criminals seem to have no qualms with breaking various serious laws (for example, attempted murder) and surely would have no problem with violating a relatively minor law (for example, a prohibition against possessing guns in a certain place), it only makes sense that potential victims of crime should be allowed to possess the means to effectively defend themselves.
Of course, society should seek out and address the root causes of violent crime and work to rectify them, but that’s a long-term, utopian goal that provides little comfort or relief to someone being confronted by a violent criminal right now.
As they say, “when seconds count, the police are only minutes away”.
