Virtue Signaling and Mass Shooting

There is an aspect of the issue of mass shootings that doesn't get much attention. Almost invariably the places where mass shootings take place turn out to be gun free zones. 

Suppose you are a budding mass shooter on your way to make your first and last appearance on the world stage playing God, deciding who lives and who dies, and you notice that the venue for your debut has a sign saying that no guns are allowed on premises. Do you A, turn around an go home or look for another place to carry out your plan or, B, ignore it? If you answered A I have nothing to say to you. But if you answered B we are entitled to ask what good can come of such signs? 

The only people that will heed such signs are the law abiding. To an incipient mass shooter who wants to have scores of helpless people begging for their lives it means one thing: victims.
