Consider also that the man is 78 years old. He's in good shape for 78, but you just don't bend like you did when you were 20 when you are 78 .I just cannot see how he could have "stayed down" and still made it to the SUV. He was tackled to the hard stage by security agents. That had to hurt, especially if he went down knees first. IMO, no one could have expected him to duck walk to the SUV, and the man is tall. I heard the SS team say "Shooter Down", then in the group protecting him someone said "Ready to get up?" and they all got up, Trump asking for his shoes (because I certainly wouldn't want to be barefoot with who knows what on the ground, thanks, so I get that), and Trump doing Trump. Standing tall, raising his fist, he is still strong. Then I heard something like "Time to go" or "Let's go" and they all started moving off stage. Oddly, it all made sense to me and I am just a bystander, not a fan. That they all heard "shooter down" and thought they were mostly safe so they stood up, but thought they should get to the armored SUV.
