Firing bean bags and rubber bullets while spraying mace into a crowd of concert goers, Los Angeles Sheriff Department deputies closed down Sunset Boulevard from Doheny Avenue to San Vincente Boulevard for two hours last night. Backed up by members of the Los Angeles Police Department’s riot squad and the Beverly Hills Police Department, LASD arrived as patrons exited a punk rock nostalgia show featuring Ill Repute TSOL and Youth Brigade at the Key Club on Sunset Blvd.
