A Belfast policeman shot and killed a dog who bit him twice when he was responding to a medical emergency. I'm not disputing that the dog, after biting the cop twice, was a threat to his safety. But don't cops carry mace anymore? My uncle used to when he was a State Trooper. I used to carry some when I rode my bicycle around Rockland just to deal with ornery mutts. I'll have to ask my brother about that, next time I see him.
