It is legal to video record and take pictures of absolutely anyone, whether they consent to it or not, as long as they are in public places, where there is no expectation of privacy. This also includes recording on duty police, and public and government buildings. If a police officer orders anyone to put away his recorder or camera, he is giving an unlawful order, and you are under no obligation to comply. Moreover, a police officer cannot confiscate a recorder or camera without a court issued warrant. What I have just stated is true in all fifty states. However, it is illegal to record private conversations.
What you are writing is, once again, incorrect.
Just because someone is in a public place does NOT mean that the person has no expectation of privacy or that it is legal to record them in this public place. For one example out of many, consider the laws against "up-skirting." There can be an expectation of privacy even in a public place.
And it is not
illegal to record all private conversations. In many states, you can record private conversations if you are a party to the conversation and in other states, you can record private conversations if all parties to the conversation consent to the recording. So, again, what you wrote is incorrect.
The bottom line is that people do not give up all of their privacy rights when they appear in public. A videographer needs to consider many things when recording, including the place, the time and the subject, and a videographer then needs to consider what can and cannot be done with the video recording once recorded. An ignorance of the laws that govern video recording can get the videographer arrested and/or sued.
The problem with what you are posting, TedMann, is that you are making "absolute" statements and, in law, absolute statements are problematic. There are almost always exceptions.
Now ... have you been arrested, TedMann, and trying to work on a defense to the charges? Have you been sued? Have you gotten into trouble for video taping police officers? Or are you just trying to learn the law?
