What I'm hearing is that a bystander stood up and drew a gun and pointed it toward where the shot(s) that hit Trump came from and was subsequently taken out by the SS.
I also watched a female SS agent, after Trump was in the Escalade, with her weapon drawn and pointed out in front of her toward the crowd. Dumb bitch. Another female agent damn near had a ND trying to holster her weapon. I'm wondering now if the moron SS agent that got robbed at gunpoint during the Biden/Clooney extravaganza in LA last month and then shot at he assailant as they were running away wasn't a female. Like 99% of the cases where Sigs go off " by themselves" involve female LEO. Jesus Christ.
