New Orleans is one of the most dangerous big cities in the U.S. and this CCTV footage is evidence of that, capturing a brutal assault and robbery of two pedestrians by a group of four men.

The assailants sneak up behind their unsuspecting victims; one is knocked out cold by a sucker punch and the other is choked out before the criminals run their pockets.

The guy who got knocked out cold appears to be in serious trouble. A truly scary moment and a sickening act of senseless violence; all for a little bit of cash and some cell phones.
