(AllHipHop News) Rap star Ice Cube has signed on to play a police officer in the upcoming movie Rampart, which will focus on the notorious unit within the Los Angeles Police Department. The flick is being written by screenwriter James Ellory, will feature Ice Cube starring as a homicide detective investigating the dirty actions of a police officer played by actor Woody Harrelson. The movie focuses on the sweeping CRASH (Community Resources Against Street Hoodlums) anti-gang program of the early 1990s that left many African-American males brutalized at the hands of police officers. Harrelson wills tar as a lead police officer who is being investigated for the beating and murder of a gang member during an interrogation. The Rampart scandal, (was) a stick of dynamite with a wet fuse. Rampart is another of these misperceived criminal conspiracies. It’s really the story of a handful of rogue, criminal cops who ratted out a wider number of untainted cops to save their own skins,” Ellroy told National Review Online in 2005. “And the entire event blew out of proportion into a media event that most people took to represent large-scale endemic corruption in the LAPD. In reality it wasn’t that. Cops are afraid to do their jobs now. There are nuisance suits filed routinely on officers who bruise the pinkies of violent street suspects, and they all have to be dealt with through the civilian complaint process. This wastes time and diverts energy from the real business of police work.”Two Rampart officers, David Mack and Rafael Perez, were implicated in the murder of Christopher Notorious B.I.G. Wallace, although the pair was never charged with any crimes and have repeatedly denied involvement in the slaying. Rampart re-teams Harrelson and actor Ben Foster with Oren Moverman, who directed the pair in the flick The Messenger. Rampart is slated to begin filming in Los Angeles this August.
