Crossing over from hip-hop to rock with his band Body Count, Ice-T's "Cop Killer" was a "protest song" against police brutality written from the point of view of a man who wants to, duh, kill cops. Released in 1992 a month before the L.A. riots, the song references the previous year's Rodney King beating and led to a considerable backlash. The outraged included President George Bush, V.P. Dan Quayle, Charlton Heston and Tipper Gore, who headed the Parents Music Resource Center censorship committee. Eventually, Ice decided to remove the song from the band's eponymous album, though Warner Bros. released the song as a free single. As you probably know, the rapper now plays a cop on "Law & Order:SVU."
