“Who wants to go down the barrel of an AR-15, even with a glock?” asked the Parkland, Fla., student David Hogg, defending sheriff’s deputies who stood outside his school while a gunman murdered his classmates. “And I know that’s what these police officers are supposed to do, but they’re people too.”

Hogg was mostly correct in this argument, but it doesn’t prove what the gun controllers want to prove. The police do not have a duty to protect you or your children. Multiple Supreme Court rulings have found that the police have no constitutional duty to protect the vulnerable. States or cities may impose such a duty on their police forces, but it’s no guarantee.
