Go to Google Earth and look at the two windows he supposedly shot out of at the concert. The window on the end makes perfect sense.
The window on the side gives him zero advantage to shoot out of. No reason at all to shoot out of that window.... at the concert.
Look straight out that window at see what he was looking at.
The airport.
Use Google Earth Pro and draw a 1200 Yard arc from that window and see how much of the charter area and General Aviation area are inside that arc.
Were the weapons found in the room even capable of 1200 yd range?
They were shooting .223 out the window weren't they?
“Look straight out that window at see what he was looking at.

Our family business has a hangar in the area just beyond the shooting scene. The FBI found bullets from the shooting on the roof of that building.
Knocking out the second window was probably for ventilation/air flow. This would help clear the room that must have been entirely chocked full of smoke.
