I found three calls for service at Glenbrook on the date in question, but none involved a weapon complaint. For gjclark, were the individuals wearing any type of uniform, and what time of day did your encounter occur? Not to be a nitpick, but "official looking" leaves something to the imagination, so if you could clear that up for me, I can run with it from there. In the future, it's perfectly okay to ask for identification from anyone who represents himself as an authority figure, whether it's a cop or someone acting on behalf of mall management. If they identify themselves as officers and escalate things or become rude, ask for a supervisor to be sent to the scene to get it sorted out for you.
