How unexpected.I want to know what the shooter was using. To me it sounded closer than the "sniper" was positioned and more like a double action revolver than a rifle. Too fast for single action and not fast enough for semi auto. Based on the poor quality sound, the gun wasn't any louder than the pistols the SS used to return fire. Which again means small arms and not a rifle.
I'm thinking that "sniper" was SS and not moving because he was busy, not because he was "neutralized." Which leaves the guy they hauled out of the bleachers as the more likely shooter.
I could be wrong.
