We covered this scenario in one of my law classes this past semester and the first reply from Denny347 nailed it, assuming my professor knows his stuff. While I don't believe in the sue happy culture out there, your friend really should talk to a lawyer and file for civil damages. They need to be penalized because, assuming your friend is being truthful, their LP staff crossed the line without sufficient evidence and will probably do it again. It's not going to be any major cash, but it will be enough to force them to review their policies and help to stop this from happening to someone else, and they'll probably settle pretty quickly on something like this (which will still have the same effect).
Imagine if your friend were armed...even if he didn't draw the store LP yokels would have found his firearm and taken it, and lord only knows if they would know enough to not put a hole in someone/something while doing it.
