That it's UK, you have offically crossed further into the DANGEROUS INVASIVE ZONES. You are not prepared to do this. Fuck you guys, you watch everyone on cameras, now you are indirectly tracking people with their phones? Eventually your entire movment will be tracked. I've seen systems like this where movement is stored, and then used to analize your places and other related things. But this those were in GAMES. Not in our everyday life. I'm sorry but this is a clear invasion into peoples freedoms. You have no right to track me or take ANY OF MY PERSONAL INFORMATION without my consent unless for some reason I am BREAKING THE LAW. They say they don't know who anyone is. Well that's a load of shit. Your MAC address is uniquie identifier. If they have that you are indirectly being stored. IF they take that they are creating a data base. IF they claim IT'S ANONYMOUS they'll default define that database as an anonymous data storage and could give open access to it to other agencies or companies. Even so, the main point is you are being tracked. Let alone all the problems and invasive issues that come along after this point. So stupid. You'll just do whatever the hell you want to.
