you were a sheriff in river city just patrolling and looking around for crime, which was often since river city had a VERY HIGH crime rate, suddenly some vehicles pulled in front of you and people got out, armed with assault weapons, they were a criminal gang and began to shoot at you, you took cover behind your car and radioed for backup, then suddenly a civilian stopped by and got his weapon out and took cover near you, and began to help you fight off the gang
