This weekend my third grader was staying with relatives. Their house is in an unremarkable subdivision of an unremarkable suburb, less than two miles from the police station, with two police officers living less than a block away. On Saturday night there was a house party nearby, which spilled outside and turned into something of a riot. Revelers used bats and clubs to smash up several cars, assault several people, and used plain brute force to push parked cars down the street. One of the officers living nearby called in a riot with shots fired. (Turns out there were no shots fired.) There was a rapid and overwhelming police response. The rioting and party ended abruptly. My kid and relatives were unharmed.
