One of the biggest lies told by the Conservatives after Newtown is that shooters will focus their attempts at violence at gun free zones because they will meet no resistance. Their solution is to put armed guards at these schools to keep the potential shooters away.

So why did this happen? That’s right. A gunman entered a police precinct and started shooting.

So much for the theory that having guns at a location will prevent a shooter from attempting gun violence. The truth is that a potential killer will commit acts of violence regardless of the risk of someone else returning fire.
