Gangs of kids love the idea. They make them look "hard", and of course they will evade the CCTV.
I don't agree. Some like taking selfies and pretending they're gangsters for the 5 seconds it takes to take the photo.
Most are wearing surgical masks or the type of reusable ones you see advertised all over the internet at the minute which are far from cool looking and get in the way of their fashion sense and socialising I have the idea that their parents have probably made them take them
