This shooting is yet another tragic example of the failed, grotesque insistence on helpless victim zones where any crazed gunman can be assured of a large number of disarmed,
I like to compare this school incident to a police station. You do not see gunmen invading police station to shoot up all the cops. Why? All the cops have weapons to shoot back with. End of story.
And...when was the last time there was a mass-shooting in a gun store?
