“As the police are public servants performing public duties and so have no reasonable expectation of privacy, I think we should start photographing cop cars with identifying information...”
LOL! Yeah, just wait & see how fast they slap an “obstruction” charge on you. Few things make a cop more nervous than being photographed or filmed in the course of doing his job.
But hey, some judge said flicking your headlights to warn traffic of a hidden speed trap is “free speech”. So there’s that...
Can't charge everybody...
Well, in this day and age, cameras can be very small and concealed. Photograph the cops without them knowing they’re being photographed.
If they see you with a camera, then you’re most likely screwed.
