More than 600 location managers, directors, actors and crew members have signed their names to a petition to the Los Angeles City Council protesting against efforts by the Los Angeles Police Department to take over crowd and traffic control at location film productions, the Los Angeles Times reported today (Wednesday). Currently the studios hire retired and off-duty officers for the jobs, but Police Chief William Bratton has expressed concern that they are not accountable to the LAPD. Those signing the petition claim that Bratton's proposal would raise the cost of production at a time when the issue of runaway production is becoming a matter of increasing concern for film and TV producers.
