You're asking me to comment in areas where I lack that depth of knowledge. I would ask you to pose those kinds of questions to a crown prosecutor. But I know from practical experience, working a hold-up detail for many years, that trying to get charges laid against people wearing a disguise is difficult, because the level of intent that's required by a crown prosecutor to proceed is, in my view, unreasonably high.
