I think Trump calling the deputy a coward makes the deputy a scapegoat and takes the heat off the rights and wrongs of too many guns in America, if he was waiting for back up as trained and in 90 seconds not knowing what exactly was going on, like one or more shooters, I don't think he was a coward no more than I think teachers being trained to shoot students wielding guns is a good idea, the world for Trump is very black and white, there's no grey area. The Deputy had a gov't issue pistol, the shooter I believe had a machine gun or more, I don't think the deputy could have done much to save anyone in the circumstances. If anything he probably would be one of the ones we be saying 'so many students, teachers and a police officer were killed'.
