As a doctor, I feel I have a duty to inform the public of what I have learned as I have observed these wounds and cared for these patients. It’s clear to me that AR-15 or other high-velocity weapons, especially when outfitted with a high-capacity magazine, have no place in a civilian’s gun cabinet. I have friends who own AR-15 rifles; they enjoy shooting them at target practice for sport, and fervently defend their right to own them. But I cannot accept that their right to enjoy their hobby supersedes my right to send my own children to school, to a movie theater, or to a concert and to know that they are safe. Can the answer really be to subject our school children to active shooter drills — to learn to hide under desks, turn off the lights, lock the door and be silent — instead of addressing the root cause of the problem and passing legislation to take AR-15-style weapons out of the hands of civilians?
