www.vladtv.com - In an extremely graphic and bizarre video out of Colorado, chaos ensues as Denver policemen chase down a man holding a knife to his own neck. In the first few seconds of the clip, witnesses can be seen frantically running around just as the victim runs out into view. The man is followed by cops around a corner, and as he closes in on them (knife in hand), one of them fires off a shot, ultimately killing him. It is uncertain if the man was still alive towards the end. According to Denver's District Attorney, the two cops involved will not be charged with any wrongdoing.
