I always thought they were just people that sometimes let the power they have go to their heads.They ain't huggy psychologists there to affirm you. They are trained guard dogs on a short leash just as soldiers are war dogs....you mess with either at your own peril...nobody calls a cop to see the best that humanity has to offer, people only call cops to see the worst, and when somebody screams and gets in their face and touches them, the very predictable happens...at worst, the guy did not know his own strength or how easily the guy would go down, and none of this lynch mob would have done any better.
