Why do so many police officers act like filming them is against the law?

@ReallyTallDwarf Dude, they get tons of more shit for making up bogus laws that don't exist in their own favor than doing their job on-camera.

I made this post because a police officer was demoted for telling a dude he pulled over that he could go to jail because of a camera in the car. The driver was a defense attorney who knew very well that people have the right to film officers on duty.
