Keystein cops?

Cop this carry on from Ha'aretz:

Dozens of Israel Police officers were injured by their fellow policemen on Thursday during a training exercise simulating violent civil unrest.

Police spokesman Micky Rosenfeld said about 45 officers sustained light injuries while practicing riot control techniques.

The majority were hurt while scuffling with each other while five others were injured when a police van overturned, Rosenfeld said.

He would not confirm media reports that the vehicle flipped after a policeman fell asleep at the wheel.

About 7,000 officers took part in the drill in southern Israel, which was the largest of its kind in state history

Maybe that'll happen during the real thing. You never know.
