I think you were pointlessly being belligerent.
The police officer actually sounded very respectful and forthright. And he has a point - it's really stupid to point things at police officers. It's impossible to know at what point you pointed the camera at him, but if it was at any time other than him standing directly beside your car and you ask or tell him prior to reaching and drawing the camera out, then he is exactly correct.
You really come across as sounding like a dithering and disrespectful moron. Sorry if you were expecting blind mistrust of police officers, but I find no fault with the officer in question.
Edit: Actually, he says "from a distance like that" so, yeah, pretty much he has a very good point (accidental shootings do happen, even to white men).
