Remember the Twilight Zone episode with the guy that built the Bomb Shelter?
The last time they had riots in Trenton (1968, after MLK's assasination), the "youths" broke into a sporting goods store and started hitting golf balls at the state troopers (who were horribly underprepared). Governor Richard Hughes (who's son Brian is now County Executive) was at a dinner part elsewhere the first night and refused to call in the national guard until he got sick of the media asking him to end the rioting in his own state capitol.
