The now-notorious violent youth riot in downtown Chicago during a recent weekend got me to thinking of a press conference way back in 2010. Chicago Mayor Richard M. Daley voiced frustration about what he said were large groups of suburban kids causing trouble on Chicago’s lakefront, even though plenty of Chicago kids were also participating, including six teens who brutally attacked an 18-year-old suburban woman. Mayor Daley complained that the youths would text each other to organize their mayhem.
