Personally, the more I think about it, the less I think he was deliberately aiming at the fuel tanks. I think they were collateral damage. Bump stock shooting isn't exactly accurate.
If you could blow up one of those fuel storage tanks by shooting it from several hundred yards away, they’d have concrete bunkers built around every one of them by now.
Not sure about that. I saw one video taken from the left side of the stage towards the center of the crowd at front of stage (most casualties located), and there was confusion at first, but no panic. No one leaving, just confused, standing up and looking around while shots were going off. So no one had been hit yet. I read somewhere that they think he tried to hit the tanks first before turning the gun on the crowd. But who knows? The FBLie certainly won’t tell us.
Well, it was accurate enough.
The scoped rifle didn't have a bump stock.
