Incompetence doesn’t equal conspiracy.
It takes two seconds to talk into your comm and say “shooter on roof clear stage”.
There were probably ten SS folks with a chance to do that—and more Homeland Security folks and more State Police folks and even local police.
The notion that none did so is crazy and impossible.
They spoke the words—but they never made it to the SS on stage.
That is rock solid proof of a comm sabotage and a conspiracy.
There is no “oops” scenario that can explain it.
