Yeah, he might want to be careful which state he pulls this stunt. He might have problems recording audio in Maryland since we are a "two party" consent state.Surveillance cameras don't usually have sound and record your conversations, or zoom in on your space.
Most people's homes are on private property, though.RV's are pretty much considered homes. I think video taping inside the RV is no different than standing outside my home and video taping inside my house. There is a certain amount of privacy that is expected there.
For the most part everything I saw was legal. That said, he was effectively, if not in reality flipping people off and specifically going out of his way to disturb peopleI have to admit that, as I am in a room where I can not turn on the sound on the computer, I watched the video clip, but heard none of the audio.
However, I think that most of you are getting too caught up in the fact that this person is using a camera. Yes, one can usually photograph what can be seen from a public setting; however, the fact that you are holding a camera does not give one license to do anything that they care to do. What would you think of his actions, if he was doing this actions without taking the videos. I expect that most would consider his actions to be quite objectionable. The fact that he is holding a camera does not make these actions acceptable.
In many states, creating an unreasonable intrusion into the life of another can lead to charges of stalking or harassment. His own video clips indicate an intention to annoy others to such an extent that they become angry. Such actions could also subject one to charges of disorderly conduct. As has previously been mentioned, some jurisdictions do not allow the recording of conversations without the consent of both parties. There can be other issues involved, but I will just keep this simple.
Again, though photography in public is rarely barred, the fact that you are involved in photography does not give one carte blanche to do anything they want, particularly where their actions are intended to, and do, unreasonably disturb the lives of others. Trying to incite violent reactions from others is not a legally protected activity.
