“Authorities have a suspect in custody after almost two dozen students were stabbed at a high school outside Pittsburgh Wednesday morning. The number of injured keeps climbing: initial reports said five to six students at Franklin Regional High School were injured, then that grew to 10. Now CBS Pittsburgh reports that 20 students sustained various degrees of injuries in the stabbing. Four were seriously injured.” The school in question is located in Murrysville, Pennsylvania outside Pittsburgh. As someone once said, the only way to stop a bad guy with a gun (or a knife) is a good guy with a gun. Of course, as we all know, our schools are sterile, gun free zones where, with the occasional exception of a resource officer, guns are prohibited. Kinda like our military bases. How’s that working out? [h/t Dirk Diggler]
