People are usually not wrongly accused of shoplifting, but if there are no witnesses, no suveillence cameras?

If the clerk saw her steal the item and/or can find the item in her possession, then the child is in the wrong. No matter what background she has, she deserves to be reprimanded because later on, down the road, she will continue to steal until it becomes a major problem and result in major jail time and serious fines. On the other hand, if the clerk does this for personal gain (i.e., attention), then she deserves to be fired immediately.
