So.. you've copyrighted the use of jackets?
I understand that you guys have your own thing and it is a good idea, that's why I and others would like the UK to have something similar. We aren't just robbing you of your "thing", we're appreciating it and considering making our own version of it.
You can't just stop other countries from making jackets for themselves because the USA did it first. Of course we wouldn't just flat out copy your entire idea, it'll probably be a different colour to make it unique for us, but you can't just say that we can't use jackets at all.
