In Idaho, a school went into lockdown, and some parents rushed to the school with their weapons to protect the children. Some brought their AR-15 assault weapons. The police stopped them and asked them not to intervene. The police were rightly fearful that there could be a shootout and a parent might be killed on suspicion that he or she was the shooter. Too many guns at the scene means bullets flying and the possibility of more victims, possibly students, teachers, police, or in this case, parents.

In New York City, where I live, the police don’t like to see civilians with guns. It is illegal and it gets in the way of law enforcement.
