Great. Part of our concern, especially in the context of the kind of conduct that we're considering here, is that the front-line interpretation is actually being done by law enforcement officers and does involve judgment calls about whether people get detained before prosecutors even get involved in making their decisions, let alone before a court gets involved.
It's a bit of a concern if lawful excuse is something that in this kind of context is not quite clear from the beginning. I asked Chief Constable Graham some questions about what might be considered to be lawful excuse. He said that we should talk to a lawyer about that, and I understand his answer.
From your perspective is it clear—and if it's clear all the better—that if a woman, for example, is wearing a veil or somebody is wearing bandages for medical reasons, two examples that Mr. Richards has given, and the event becomes a riot or an unlawful assembly, continuing to wear either would be a lawful excuse?
