None of us were there, but it could have been a case of the 2 dispatchers finding themselves in a dangerous predicament - one which was gathering momentum by the minute. I am not condoning their actions (whatever they were), but threatening behavior is one of the first things I though of.
It all goes back to the public's expectations of anyone in uniform, and reason enough to go "Clark Kent" when off the clock.
