I don't think disarming the officers is the correct answer, but you better bet your ass I'd sue (or would hope my famiy would, had I been the victim)! I know it's easy to armchair a situation when I wasn't there, but that sounds like really poor control of the situation on the part of PSU security and a lot like a "shoot first, ask questions later" type of response. Any non-LEO person would be hung out to dry. The outcome of this should be interesting.
