Man demonstrates a machine gun which is attached to the front of the sidecar of a motorbike. We see this first in C/U then from another vehicle as the motorcycle and sidecar is driven along. M/S of two policemen driving an open topped car who are firing at the sidecar. The policemen fire frantically as if chasing gangsters. M/S of an old jalopy having bullet holes pumped into it. Man in military uniform crouches down and fires at the car. M/S of the car on fire. "A thousand shots a minute... they'll keep away from this 50 gun-power policeman." M/S of man firing machine gun. M/S of a barrel which spurts water from many holes where policeman has hit it. M/S of the policeman firing at barrels (he isn't in uniform).
Note: might be good for illustrating cops and robbers type stuff - police chasing bootleggers or something of that sort.
