Ann Coulter " School shootings that have been halted were almost always stopped by the happenstance of an armed citizen on school property."
....In 1998, a student attending a junior high school dance at a restaurant in Edinboro, Pa., started shooting, whereupon the restaurant owner pulled out his shotgun, chased the gunman from the restaurant and captured him for the police.One dead.
See the pattern?
In response to Columbine, schools adopted "anti-bullying" policies; in response to Virginia Tech, eBay ceased selling magazines online; in response to the Tucson shooting, liberals want to ban the particular magazine Loughner used." And then the next killer will come along with a different arsenal and a different motive, and the only way to stop him will be with an armed citizen with a gun."
