Drive to the crime scene.
Follow the red running man icon to 1624 West 3rd Street 
. When you arrive, a uniformed police officer briefs you on the situation. The Third Street Gang and the Diamond Street Gang are on the brink of an ugly rumble, but no bloodshed yet. Shots are fired just before the cinematic ends.
Subdue the armed suspects.
You begin this gun battle crouched behind the hood of a police cruiser. Remain there and begin firing at the nearby gunmen hiding behind cars in the parking lot. For a much clearer and easier shot, wait a few moments without firing and a couple of the closest suspects leave cover and advance toward you. This is when you should pop up and gun them down.
Run toward the bodies you dropped and find cover behind a nearby vehicle. When you have an opportunity, pick up one of their dropped weapons. From this new position, you can take out the remaining four gunmen, who are covering behind vehicles further ahead in the same parking lot.
After gunning down the sixth thug, a car drives up in the distance to offer support. Now there are two more gunmen to subdue. Move forward safely while using the cars for cover. Fire your weapon to take the additional gunmen down quite easily from a safe distance.
