 It seemed textbook to me. Thereafter, though, it's hard for me to understand what happened because a couple of seconds later, after more shots had been fired and maybe a minute or so later, everyone stands up. They're still surrounding Donald Trump, protecting him with their bodies. But there's that moment where in the audio we hear Trump say, wait, wait, wait. And he then pumps his fist to tell the crowd that he's OK. Is that protocol?
