Five shotgun bullets and free police cruiser.
When you find a taxi and a police car nearby each other punch the taxi. If he/she gets out to fight run in front of the police car. Let him/her punch you and the cop(s) will attempt to arrest him/her. Both police should get out. Get in the police car if both cops pursue the driver. You will get five bullets for shotgun and a shotgun if you don't already have one. The worst thing that could happen is having to escape the police.
