"Walmart detained them, the police came and cuffed one of them, their two kids were taken to a security room..."Sue them for millions. That, right there, is kidnapping, pure and simple. Not the part after the cops arrived, but the first three words of that sentence. The law is very clear on this point. A store has absolutely zero legal authority to detain you if they suspect you of theft. Their legal recourse is to call the police without confronting you and have them deal with you when they show up.It's the same reason stores tell their employees not to follow you out of the store if you've shoplifted. The legal liability greatly outweights the benefits of saving a stolen good.This situation is the same, only it is now both criminal and legal liability. So, if you've been exonerated by their own security footage, hit them in the only place a corporation understands: their bottom line.
