It's amazing how this thing was nailed by former Military vets on FR. They tied the sniper to Military training and also said two were involved, one shooting and one driving the get-a-way car.
Maybe they should get the reward, if this pans out...:~)

I think John Williams got his "training" at a civialian installation in Alabama. He was in the military, but likely only received basic firearms training. He was almost certainly NOT an military sniper. It was reported that he was Dishonorably Discharged from the Army.
