WASHINGTON -- 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, North Carolina, police of how they came to fatally shoot Keith Lamont Scott on Tuesday. Scott's killing prompted two nights of violent protests that led Gov. Pat McCrory to declare a state of emergency. On Friday, police in Tulsa, Oklahoma, 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.

This is crazy, in my humble opinion. I believe that we should try to save some of the 30,000-plus lives lost each year to gun violence by enacting sensible firearms restrictions -- and that the more people who walk around packing heat like Wild West desperados, the more deaths we will inevitably have to mourn. In its wisdom, however, the state of North Carolina disagrees.

We should continue to lobby for tighter gun laws and hope that someday the voices of reason are heard. But at the same time, we should demand that current laws be enforced fairly even if we don't like them. Scott's death is the second recent police slaying to suggest that laws permitting people to carry handguns apparently do not apply to African-Americans.
