 We heard something that sounded like a firecracker, and we turned around, and there was people behind us, and it was two of our guys, I think, in camo uniforms shooting back. Everybody started cheering once they got to the shooter. You could see them up on top of the building. We literally watched them shoot back. I mean, they were right there. We started yelling, hit the ground, hit the ground. When I looked over, then I saw the smoke from the gunfire.
