NYPD Practicing Riot Drills

NEW YORK - APRIL 06:  A New York City police officer stands on patrol on April 6, 2010 in New York City. Following a melee involving groups of youths around Times Square last Sunday evening, concern is growing that New York City may be witnessing a resurgence in crime. Crime is up while fewer officers are patrolling the streets due to budget cuts in the police department, with more officers assigned to terrorism related security details. Shootings in New York City are up 19 percent and murders up 22 percent over the same period last year. (Photo by Spencer Platt/Getty Images)

The New York Police Department's apocalyptic-sounding Disorder Control Unit spent the weekend rehearsing for deployment in the event of local riots like those that struck England last week. The "mobilization exercise" took place on Randall's Island and featured 180 officers both on horses and in the sky. Is this supposed to be reassuring? [Metro]
