Sheriff Lyle opening fire with the M60
Not only are there civilians all over the place, but you can clearly see cops and national guardsmen running around behind Duck's rig, directly in the line of fire, and Lyle is just blasting away with that machine gun.
How many crimes committed by Sheriff Lyle and the NG troops here is anybody's guess. The Sheriff isn't even in Arizona, so he has absolutely no authority to man a machine gun like that and open fire on a civilian, not even if the Governor of Texas said he could. The Governor should be in a heap of trouble about this too.
