An idiot who starts talking about his personal "right" to observe and record the police while they do their jobs, instead of backing off, is interfering with law enforcement.
And, if you are polite and respectful and the cop still treats you badly, document it and file a complaint. When a civilian complaint review board reviews the complaint, they will investigate the officer's conduct and yours, and if you did what you were told to do, and didn't make a scene, and were still spoken to in an abusive or disrespectful manner, or worse, they will come down on the officer.
