Jack, they Do take orders from a "Heid Bummer". A Muslim friend of mine who runs a fast food shop in the city was reduced to a shivering wreck after a visit from his local "Heid Bummer" who dressed him down for some misdemeanour.
The guy pulled up in front of the shop in a snow white limo, walked straight into the back on the premises in full Islamic gear plus sunglasses.....he was well over six foot and built like a brick shithouse.....I asked my friend what had happened, he couldn't speak, just shook his head....in time with the rest of his body.
