At least my SCA armour is safe - until some other ban-nut has a tryst with the Good Idea Fairy.
Apparently, those with firearms licences are also exempt.
Are old steel military helmets exempt, or not? Helmets are not mentioned and, in fact, the whole thing seems a little vague to me.
One wonders if there have been any legal challenges, yet.
This is stupid legislation, anyway, and harms only the law-abiding. Just make it illegal to be a criminal, regardless of what items one has in one's possession.
