I was all set to say give her a break....she probably was lost in the moment and lets wait to hear her answer the criticisms with an explanation.
Then I see the photo and she has her right fist clenched down by her thigh.
Photos can trick the eye with the snapshot in time....but to me it looks like she is contemplating oerforming the black power salute and cannot muster the courage so she is doing it surrepticiously.
Interesting.
