'Bach attack'

Is this going to get the 'hip-hopping' individuals to move? Definitely. Will it remove the problem? Probably not.

I have mentioned this before, but it's worth repeating. While I worked the doors, smart DJ's knew how to "remove" unwanted individuals by playing music they absolutely hated. Also the (good) DJ's could often times spot brewing trouble and use music accordingly.
Needless to say - one of the best ways to get people out (and alert the bouncers) was to stop the music immediately when someone started a fight.

Story:
Washington -- Tacoma city authorities, fed up with gang activity in public places, are taking Bach their bus stop.

Transit workers are installing speakers this week to pump classical music from a Seattle radio station into the Tacoma Mall Transit Center. The tactic is designed to disperse young criminals who make drug deals at the bus stop or use public transportation to circulate between the mall and other trouble-prone places.

The attack by Bach, Brahms and Beethoven follows the theory that prompted the city to stage pinochle games on dangerous street corners: Jolting the routine in such spots throws criminals off balance.

"It's based on routine activity theory and situational crime prevention. You mix different types of activities in locations that are crime-ridden to change the composition of the environment," said a psychologist who chairs the Criminal Justice Department at Seattle University.

A 19-year-old male said troublemakers won't like the orchestral strains, but they'll probably just move somewhere out of earshot.
