USAF style crash trucks with white or red dye in the water cannon ...... supported by a few hundred stomp and drag riot control sorts backed up by SWAT sorts in lenco bearcats using the boomerang fire direction finder system to detect shooters exact positions etc ..... add in a few dozen prison buses to take prisoners on a slow hayride etc..... voilà !

Get on the road and block traffic, get zapped, heave ho...
