In the wake of Columbine, the law enforcement community did a lot of soul-searching and arguing and seminar-convening over the proper response to an "Active Shooter" scenario. The general consensus that emerged seemed to be that when innocent lives are at stake, first responders should saddle up and roll in on the psycho, hopefully putting him on the defensive and thereby minimizing the body count. Mark Steyn points out that maybe that memo didn't get circulated as widely as it should.
Let me get this straight: You don't want me to be able to bust caps to save myself, but you're not going to do it for me, either? Thanks so much for the concern. What am I paying y'all to do, again, exactly? As Marko is so fond of pointing out, the only thing that stops a spree killer is a gun. The body count is determined by whether the gun is already on the scene or needs to be carried there in the holster of a cop.
