My own personal opinion is that if two cops are in the car, one should be assigned an M4 (or P90). And said M4 should stay with that cop everywhere the cop goes. (Need to take a shit? Learn how to do it with an M4). As the driver approaches a vehicle, the M4 cop should have the weapon at ready. This would eliminate many would be shooters from attacking. As soon as this guy stepped from the vehicle, a trained cop with an M4 would have eliminated the threat before any round was fired. People are crazy, we need to always account for that.
