To all the people who hate being filmed...
Number 1, you are filmed by 100s of CCTV cams every day.
Number 2, there is no expectation of privacy in a public place and you don't need someone's permission to film them in public. Even if what you are filming is not public, if it can be seen from a public place you can film it.
Councils, companies TV co's etc don't get special permission to put up cams that look or film into public places, that's the law.
I don't believe that it is possible in law for filming to cause alarm, harassment and distress otherwise anyone could claim that of CCTV cameras. It would be laughed out of court, although I have seen cops try it on with Joe Public. Mind you, I have seen a lot of cops make up laws to try and stop people doing lawful stuff or make them do something they don't want to do. Like the copper who dragged someone out of their car because they refused to get out. They may like being in control, but it is not law that you have to get out of your vehicle when asked by a cop, unless you are being arrested. Even if you are being breath tested, you can stay in your car.
But IME cops hate it when you don't do what you are told, even when that is a load of rubbish they have just made up to suit them.
