So we are learning more about the raid on Mar A Lago thanks to Julie Kelly.
I can explain this real easy, it is kind of like this with a few differences:
So if we made a few changes, first they had many agents, not just one. Second they were instructed to shoot to kill if necessary, so put guns on these guys. Third, they were instructed to not identify themselves or show badges, just to make it even more interesting. Finally, if Jerry had Secret Service agents there sworn to protect him, increasing the chance of a shootout even more.
