I am sure the cops and SS folks who saw the shooter climb the roof notifying command and control.
The conspirators were command and control.
That is why nobody on stage got the word.
This was not incompetence.
This was premeditated attempted murder by moles in the Secret Service.
I believe that as well. Too many ways that eased the path to an assassination. Biden's people (meaning the ones who pull the strings on that senile puppet).
