This is from Philly.com not exactly a conservative bastion with some startling revelations:

 

Since at least 1950, all but two public mass shootings in America have taken place where general citizens are banned from carrying guns. In Europe, there have been no exceptions. Every mass public shooting has occurred in a gun-free zone. And Europe is no stranger to mass shootings. It has been host to three of the six worst K-12 school shootings and by far the worst mass public shooting perpetrated by a single individual.

Still, Kelly said, “There’s no indication from other — from another study that any shooter intentionally went to a gun-free zone.”

Kelly might be surprised to learn that killers have frequently talked about their desire to attack where guns are banned. The suspect in the Charleston, S.C., shootings in June originally aimed to attack the College of Charleston. He chose a church instead because the college had armed guards.

The diary of the Batman movie theater killer, James Holmes, was finally released just a few months ago. He decided against attacking an airport because of the “substantial security.” Out of seven theaters showing the Batman movie premiere within 20 minutes of the suspect’s apartment in 2012, only one banned permitted concealed handguns. That’s the one he attacked.

Or take a couple of cases from last year. Elliot Rodger, who fatally shot three people in Santa Barbara, Calif., explained his reasoning in his 141-page “manifesto.” He ruled out various targets because he worried that someone with a gun would cut short his killing spree. Justin Bourque shot to death three people in Canada. His Facebook page made fun of gun bans, with pictures of defenseless victims explaining to killers that guns are prohibited.

Americans seem to understand these points. A June Rasmussen Reports survey found that 68 percent feel safer in neighborhoods where guns are allowed, while just 22 percent would feel less safe. A Gallup poll last December found by a whopping 63 to 30 percent margin that Americans thought guns in their homes made them safer.

If you don’t think deterrence works, ask yourself if you would post a sign in front of your home saying it is a “gun-free zone.” It’s very likely that such signs aren’t going to be going up in any neighborhoods soon.
