Perhaps but if he knew what he was doing, he would have brought along something capable of penetrating the steel tanks at that distance.
The pauses between bursts saved many lives.
The position of the tanks were more a direct line with the broken window in the smaller room, while the window in the big suite was directly in line with the concert fair grounds.
I’m saying it’s possible the pause was he first shot at the tanks (from all the ear witnesses there that night) then began spraying the crowd the pause could have been switching windows??
idk
