An AP round would pop the window. The music was pretty loud and distance significant between the hotel and field. The breaking glass would have been less noisy than the rifle rounds. It was smoke detectors set off by the burning gun powder that identified the shooter's location.

The glass had to come down below and as if there wouldn’t be people at the hotel at 10pm at night hearing the commotion on their floor or around their rooms? The smoke alarm makes no sense. Those at the concert closers to stage heard and thought firecrackers.
