“police and SS were on different radio channels so the communications were all screwed up.”
Even if true that explains nothing—because the SS folks outside the stage were notified by witnesses that a guy with a gun was on the roof.
The SS internal comms had to be either sabotaged, jammed or stopped by a central comm location—regardless of what was happening with the local LEO.
I agree. There was no excuse for them not keeping Trump away from the podium.
If the SS internal comms were deliberately sabotaged it would make it easy to prove this was not just mind-bogglingly-impossible incompetence, which is what they’re going to try to use as an excuse.
The point in all of this is how to prove that it was deliberate and not just incompetence. Communications sabotage would be one way to prove that, if that could be documented.
If it is true that the snipers requested and were denied permission that would be another way to prove that the assassination attempt was deliberately allowed.
