I'll quote the opening sentences, for emphasis...because this is how an official response to such an incident should read:
“This employee is protected under the Second Amendment. He followed all policy and procedure at the school, and in this particular case, did everything that he should have done to protect the innocent lives of the children at the school,” Lt. Brian Eynon of the Ogden City Police Department said. “And in this case, it is likely that a life was saved or injury to a life was prevented due to the actions of this heroic employee.”
Sadly, had this happened in NJ, our Governor and his lapdog AG would have made sure the teacher died in prison
