It's a zombie apocalypse underway in crime

A naked man leans over his nude victim tearing chunks of flesh from his face with his teeth which he readily consumes. An officer approaches and orders the crazed man to get off the victim, the man looks up at the officer blood dripping from his face and growls like a wild animal then continues to devour the victim. This is not a horror film, it's a macabre attack in Miami that some people are understandably calling the start of a zombie apocalypse. Grab your, uh, popcorn.
