The Huge "Gate" we see above is closed/ajar. If we could see the other gate, we would see the 2 gates are roughly 2 feet apart. The Three Tramps photo shows these gates to be in the same position we see above. Closed/Ajar. The Three Tramps photo was taken close to 2 hrs after the Kill Shot.
Wrong again.
In the Allen pic below we can see the space where the Huge Gates are is just a rectangular black void. There is no diamond pattern discernible meaning the gates are still "wide open".
The Hertz clock on the TSBD building reads 12:40pm.
The Huge Gates were still open at 12:40pm.


As I've already told you, I dealt with this issue years ago.
All it means is that the building was not properly locked down for at least 10 minutes after the shooting.
As I've already stated, the door on the west of the building was never locked down so anyone could come and go as they pleased through that door.
Your made up nonsense about the Huge Gates all being part of a professional plan is a joke that only you don't seem to be getting.
