Its a coverup of incompetence. A cover up of negligence. A cover up of DEI policy failure. A cover up of inciting the conditions that encouraged and allowed a wing nut to take a shot.
I dont see conspiracy. I see lots of finger pointing when they created the situation. They wished it to happen, wanted it to be successful. Will deny their culpability. But are embarrassed to be shown for their failure, before and after.
Focus on command and control.
That is where they key to the conspiracy lies.
