If you are a black man in America, exercising your constitutional right to keep and bear arms can be fatal. You might think the National Rifle Association and its amen chorus would be outraged, but apparently they believe Second Amendment rights are for whites only.

In reaching that conclusion I am accepting, for the sake of argument, the account given by the Charlotte police of how they came to fatally shoot Keith Lamont Scott on Tuesday. Scott’s killing prompted two nights of violent protests that led North Carolina Gov. Pat McCrory (R) to declare a state of emergency. Last Friday, police in Tulsa shot and killed Terence Crutcher — an unarmed black man — and the two incidents gave tragic new impetus to the Black Lives Matter movement.

Scott’s relatives claim he was unarmed as well. But let’s assume that police are telling the truth and he had a handgun. What reason was there for officers to confront him?

North Carolina, after all, is an open-carry state. A citizen has the right to walk around armed if he or she chooses to do so. The mere fact that someone has a firearm is no reason for police to take action.
