He's definitely carrying his keys on his belt like a rent-a-cop would. I've never seen an actual police officer have his keys swinging around from his belt like that. It certainly wouldn't surprise me if he wasn't a real cop. Pretty unprofessional from what I can tell. And yes, I've seen plenty of armed security guards.
