I felt exactly that way myself. The officers, when confronted about it, were angry and defensive, saying that they didn't know how many shooters there were, and where they were. One of the shooters was spotted outside the school only 60 yards from one of the officers. While that's a difficult shot for a handgun, it takes literally only seconds to close that distance and engage the shooter.
engaging the counter-girl at Krispy Kreme is much more pleasant - and safe. :(
