I see both her arms behind her back in every video I’ve watched.

I haven’t seen any video that is a mirror image.

Thanks. I watched the best version I have, and agree with you. Both arems bent and held tense. Could well be a taught position to facilitate being handled. He left hand looks likes it's shaking a bit.

CNN calls it "stumbling" and "appears to lose her balance as aides assist her into the van."
