Very good points.
Although having a second room may have been a way of hiding for just a bit longer. It sounds like SWAT broke into just the one door - not sure why they didn’t enter both.
Maybe the security guard said “So I was at the door and he started shooting like crazy at me and hit my leg. Then I heard a single shot, and then it was quiet.” (I was going to have the guard hear a “thunk” after the single shot - but I’m guessing after all of that nearby gunfire his hearing was shot.)
HMMM - the photo of the shooter in the pool of blood - no hearing protection iirc. That seems odd - with all of the planning that he did. Maybe THAT’s why he didn’t fire the remaining hundreds (thousands?) of rounds he had.
“Geez that’s loud - I can’t take it anymore!”
I looked at the photo again. I don’t see any hearing protection. I think even a small foam plug would have been visible sticking out of his one ear. I can’t imagine shooting a gun at least once and realizing how loud it can be. And then trying to do it inside. It’s not like in the movies where they have the shoot-out in the room and nobody reacts to how loud it just was. “BANG, BANG, BANG.” Then whispering to their partner - “Cover me.”
On one site it shows a photo of blood on his stomach claiming he shot himself twice! Pretty sure it is just splatter coming from out of his mouth, across his chin and landing on his pot-belly.
