In 2006 Michael Gannon of Nashua, New Hampshire, was arrested for recording police in his own home, despite having a warning posted that the premises were monitored by a surveillance camera. And last July, 20-year-old Adam H. Whitman of Portsmouth, New Hampshire, was arrested for recording cops who had raided a party where they suspected underage drinking. Both Gannon and Whitman were initially charged with felonies. Charges against both were later dropped.
It looks like there are places in the USA where right now you would be required to turn off any and all video surveillance (inside your own home) when the cops arrive, who are they free to beat the crap out of you if they feel like it. The felony charges will eventually (probably) get dropped, but you're still left with any abuse suffered.
