Your an army man Dev , why no recoil from the AK47 or blood from the point blank range head shot on the pavement ?.
I've fired an AK, there's very little recoil. As for the blood, it doesn't all come out at once when someone is shot. When the Cop was shot the camera never lingered on the scene or it would have shown the blood pooling as he bled out. Maybe the Cop is still alive, who knows, maybe he's the new World Hide and Seek champion.
His family were actors too no doubt SN, and the other Cops who knew him, plus all the Charlie Hebdo employees killed, all actors, now sadly out of work because of the fear of being typecast.
