No one wonders if the SS left the roof uncovered on purpose so the shooter could go there.
The entire world knows the SS is as corrupt as the rest of DC and likely in on the attempt.
I assume that's not meant to be serious. It is perfectly reasonable to speculate that the Secret Service left the roof uncovered so the shooter would be able to kill Trump. The Secret Service had a glaringly obvious professional duty to cover the hell out of that rooftop. They can't now say, "Oopsie, our bad! Silly us!"
