Until 1969, virtually every public high school in New York City had a shooting club. High-school students carried their guns to school on the subways in the morning, turned them over to their homeroom teacher or the gym coach and retrieved them after school for target practice. The federal government even gave students rifles and paid for their ammunition. Students regularly competed in city-wide shooting contests, with the winners being awarded university scholarships. It's a price to pay that some demagogues would not like to understand.
Power tends to corrupt, and absolute power corrupts absolutely.
Great men are almost always bad men. The Israeli reaction to terrorist attacks on schools was to arm all the teachers, and have field trips accompanied by volunteer, armed parents. Terrorist attacks ceased.
