This could be dragged much deeper than you think. Some clarity:

1. Did they find anything in her pocket and her bag? 2. Does she has any previous official records?

The answer to both is NO then she can approach this two ways

Easy way 1. Go to the court and say she was falsely accused, they will have to provide video evidence to establish guilty and then re-sue them for $1K for metal trauma, lost work, personal expense. Courts easily approve those.

Not so easy way 2. Hire a lawyer, and make this a racial profiling. Lots of $ and time. Talk to couple of lawyers who do it for free but take a cut from winnings. This may be more than 60% if they see this as legit litigation issue. Not sure anyone has time but corporations.
