Billy, are you saying that they did not have resources to cover that rooftop that was in plain sight of the stage? Or is it SS procedure to wait for a would be assassin to fire first before taking any action whatsoever to stop more shooting?
I have heard a recording of the SS guys talking about the guy on the rooftop, pointing him out, and doing nothing. If that is normal protocol, I suggest a new protocol be developed where such rooftops are not left unmanned and if so, someone on there gets shot, especially if they have a firearm. Even if they don't.
