From what I recall of training video, it's not "just throw stuff at the bad guy", it "Throw stuff, then follow it in and swarm the bastard." Crap flying toward the Bad Guy gets him to stop shooting/duck, which gives the 10, 12, 20, 30 folks in the room a chance to jump the the guy and beat the snot out of him. 15 or so folks sitting on his chest after they've punched and kicked the crap out of him will definitely take the fight of him.
