It's not a disgrace. The employer isn't being arrested for charges of battery or assault... THAT would be a disgrace. But had that manager been STABBED while trying to apprehend a knife weilding shoplifter, that would have cost the company tens of THOUSANDS. A company doesn't stay in business by putting tens of thousands at risk for a $15 (or whatever the cost of the item that was stolen) item.
