Bad guys don't follow laws
Chicago, Aurora, indeed, most of the world all have laws against murder. And yet they occur. Chicago also has strict gun control laws and yet, as detailed here in American Thinker and other places, shootings and murders occur almost daily. Why the seeming contradiction?
Former Alaska governor and former Republican vice presidential candidate Sarah Palin bluntly answers this question, saying what most people know in their hearts.
Asked whether the shooting should affect gun policy, she said, "the bad guys, the criminals, don't follow laws and restricting more of America's freedoms when it comes to self-defense isn't the answer. Not when you consider what the reality is. Bad guys don't follow laws."
And there you have it. A punk in a gang, out to protect or expand his (and it is mostly male) territory will not be stopped, or even consider, some artificial laws (to him) against guns or murder. A deranged person operates under different reality from the surrounding society. Slightly inconvenienced perhaps in obtaining a gun, inconvenienced again maybe in some attempt to disguise his crime but because "bad guys don't follow laws" the bad guy will do what he's gotta do.
And that's the reality.
