then focus your attention on the position of her arms, which appear to me to be handcuffed behind her back.
and then she has trouble walking, short strides, and there is a distinct "clink" noise as she walked.
that would be consistent with someone walking in shackles.
the only problem i have with this is why would they have her cuffed in public if this was mean't to be kept a secret
