Yes, firing a gun in a crowded subway station is absolutely in the wrong, as we can see by the three innocent people shot, one in the head. There are police forces across the world trained to deal with assailants with deadly weapons including knives without shooting them. It’s reasonable to expect the NYPD to have the same level of training and judgement.
“I need you to be able to tell me what’s wrong with this without me explaining it verbally.”
