From the movie Demolition Man, starring Sylvester Stallone and Wesley Snipes. It was repeated, along with a police code (1-8-7) over police scanners when Wesley Snipes' character had escaped from cryogenic prison into a crime free society, where he perpetrated many murders.
Police Scanner: Code 1-8-7. Murder-Death-Kill.
