How do you kill the snipers in Silent Edge Final Fantasy the Dirge of Cerberus

I find it easiest if you stick to the edges around that area, there are 8 snipers in total.

1- Stood behind an arched opening to the left of center from where you enter, on the roof of a building.
2- The far left of the arch on the roof of one of the short buildings to your left as you enter.
3- On the bridge across the town center on your left as you enter.
4- Farther to the left at the same height as 3.
5- Move just out from under the arch where enter from, aim hard left up at the bridge.
6- Stay in the same position, just swing around hard to your right at the same height as 5.
7- Just to the left of 6, but higher up.
8- At ground level. Move left along the perimeter of the town center to the third alcove, and then aim directly across from you. Next to a white crate.
