Butler Witnesses behind Bleachers saw Muzzle Flash

Cullen might bring this guy on his show who shot the video. Let's see. This would be a totally different gun than the one(s) thought to be in an AGR 6 lower window. Cullen posted an article or someone did in his comments, a long time ago about a sidearm being fired behind the stands. I didn't save it and now he blocked me so I can't find with advanced search, but you can, and if you do post a link or screengrab here in comments, you can use imgur to share photo links.
