“I am now convinced that communications on site (LEO, SS) were jammed in some way”
Possible. I’m not even kidding. The goofballs in the old Keystone Cops films had it more together than these guys did on Saturday.
Look at the well known film of the women SS agents on stage.
They were totally confused—had no idea what to do next.
That means nobody was on their comms giving them instructions.
