Well, the looters come out of an intersection to the south. If you're looking to the north, there's a billboard and a brick fence to the left. On the otehr side of the fence, there's a gas station. That should help. You want to prestage your units. You should have 1 SC with 2 marksmen and as many cops you could fit. Then, you should have 2 police cars, each with 2 officers. Then, equip the marksmen with flash grenades, and when the looters come, throw them. Have each unit arrest a looter. Leave them there and put 1 looter in the SC and and go arrest the hacker!
