This just goes to show (again) that common sense isn’t so common. Two St. Louis teens, ages 15 and 17, were almost immediately arrested after they recorded themselves taking part in the infamous knockout game. As you know, those that do it usually record it — and that’s just what got the teens caught. In the video, a group of teens are walking down the street alongside their “victim.” Once he turns away, he gets punched by one teen before the other begins to kick him in the head. See it after the jump.
