Silly comparison. There is no reason for people to wear a full-face helmet in public. There may be a reason for people to know self defense though, which is why some martial arts clubs go out on the town with the specific goal of beating someone up: to remind that person and everyone else sees it that they need to know how to defend themselves. Sure, life would be grand if no one ever broke into computers. Security is expensive and not remotely fun. But there will always be someone out there motivated to break in. It's good that these guys are doing it publicly. The more common and nasty ones keep their mouths shut and use our machines to do bad things. EDIT: Made the text a bit clearer.
