Re: Surely they have to go shopping?
Not the entire point of the story tho and it does 'not' set a legal precedent, so I wouldn't worry about it. The core issue here: Harassment.
You can record CCTV etc if it's to combat criminal activity...
But this clown setup cameras, lied about it, did it to the point of sheer harassment and when he didn't get the reaction he wanted, then used those cameras on their neighbour to attempt to exact revenge for an earlier argument.
