Dallas PD had a team that used our building roof each year during the Cottonbowl back when it was still in Fair Park. They brought along a good bit more gear than is shown for the Superbowl.
Sorry, I was referring to the other pics where a couple of officers are aiming the the rifle into the seats. Some spectators are visible in the seats on the side.
If a hunter did this in the woods he would be chastised severely.
