He did have absolutely no right to carry around a 12-foot-wide display and scream bloody blue murder. Yet I can’t help wonder what ELSE he did in those moments which were conveniently edited out of the video, immediately before the confrontation got physical. Let’s see, he was charged with threats, and challenges to a fight. Before the gap in the video, the security guard is talking quitely and calmly while he’s raving like a lunatic; after the gap, he’s belly to belly with a police officer who grabs his hand. Gee, you don’t suppose there’s something in that edited portion that the editor doesn’t feel makes his case very well, do you?
Security had no business bugging him in the first place. They fired him up. Lotsa cops do it deliberately and security personnel aren’t trained to so much as a walk a dog let alone deal with people in tense situations which are usually of security’s own making in the first place.
