Judge Sets Bail at $1 Million Each for Lancaster Rioters
Rioting in Lancaster, Pa. in the wake of the police shooting of a knife-wielding man has led to the arrest of 12 adults and one minor, nine of whom are being held at Lancaster County Jail on $1 million bail each.

The arrests happened during a riot around 3 a.m. Monday that saw demonstrators marching from the scene of the shooting to the police station while throwing glass bottles, rocks, bricks, gallon jugs filled with liquid and plastic road barricades at police, authorities said. A county vehicle was also damaged.

Good. This kind of acting out is not tolerated in two-year-olds and it should not be tolerated in adults. Drive that point home enough hard enough and the behavior will go away - simple as that.
