Re: Not many lawyers here on El Reg
However, I presume it is almost impossible to determine whether the GG is on from a distance. Therefore, to maintain the law, police will have to assume that it is on if you are wearing it. Why else would you put up with looking like a massive member? Surely you will have a spare pair of glasses for when you have no "need" for the GG functionality (and you don't want to look like a dork)?
