Buy him a gun. There are lots of bad ideas circulating about how to protect our children from school violence. They include the promotion of snitching and increased surveillance of our children — who are already under nearly constant surveillance by public school employees. Among the worst ideas is the notion of the “gun free school zone.” Along with schemes to register guns and watch gun owners like poodles on the lawn, the idea of disarming those who would protect our children from harm is as senseless as it is patronizing of law abiding gun owners.
