> The guy was not infantry. His main job was construction, and his training would not have included advanced techniques. He was nothing like a Marine sniper.

Yeah I know (construction and masonry) but still combat training in boot camp which is better than the average citizen gets.

My SIL was Marine Infantry. He’d be scary if he was evil. My son was Army Guard, construction. He’s a good shot, but only because he likes to shoot and practices. I was USAF. I had a chance to get some extra training from the Army and took it, but I wouldn’t be scary at all. The Army training I took emphasized teamwork and included things like grenades.

The shooter wasn’t actually very effective, given a target-rich environment, night, surprise and good body armor.
