Should it be allowed to wear Google Glass in public places where people may feel uncomfortable being filmed?

But filming should be allowed ONLY after the person taking the pictures has gotten a written release from every single person who may have been or will be filmed (unless friends or family, of course, but with the laws not exempted in the event friends and family don't want to be videoed), else stand the likelihood of facing, and losing, civil lawsuits based on infringement laws.
