Hillary's right arm is bent, hand behind her. As she is moved from resting against the bollard toward the van, she does not move her hand or arm, it stays bent in exactly the same position. People always move their hands and arms when starting to walk, unless they are doing some act where they control their arms for some visual/dance purpose. She's out of it while propped on that bollard.
Good observation. She was indeed out of it.
The way she bobbed, I wondered if she was having an episode, but I’m not convinced she was now.

Pointing out Cheney, and GWB's fainting.
