A valuable lesson in how not to react when a cop pulls you over: A Colorado man who was pulled over for driving without his headlights just after 2am today exited his car and opened fire at a police officer with an AR-15-style rifle. The cop survived uninjured, but the unnamed 28-year-old suspect was not so lucky: The officer returned fire, shooting him at least three times, the Coloradoan reports. The suspect had to be airlifted to the hospital, and is now in critical condition. (It's been a rough week for Colorado police; another officer got kicked outside a bar on Monday.)
