I don't recall that from Tricia's interview. I recall him saying the crew on the stage did a lot of things right, some wrong.
Begin @ 25:20 Jim where says that the only thing the agents did do right after he was hit was pile on Trump and after that they did everything wrong.
The height of the female agent left
Trump exposed and vulnerable to be shot and they never should have agreed to getting his shoe and him standing there agents know the danger and ignored the possibility of a second shooter and should have gotten Trump surrounded with his head down and into the vehicle ASAP.
Once Trump was shot and in danger it's the SS's call on how the situation is to be handled and not the presidents.
@25:20 Jim begins his critique.
