I just saw that. That is incredible. Walking around on the roof in full view. They had to have seen the rifle.
IMO, that means someone was telling the snipers to hold their fire. I don't think they would mistake him for a police officer. I don't know why the snipers would not fire when they saw the rifle pointed at Trump.
And someone in charge there didn't get Trump off the stage. Could be incompetence, but it is very easy to move to intentional.
I remain astounded by the rules of engagement that people are claiming are in effect. I am incredulous that the Secret Service is hampered by a "do not fire until fired upon" mandate.
They have a reputation of being willing to trample/maim/kill anyone in the process of protecting their Principle, quadruple-plus-so if that Principle is a Head of State and to the Nth degree if it's POTUS. Law doesn't matter, and the entire world is an active battlefront. It just needs to be subtle until the lead is actually moving, then subtlety is for losers.
