Re: BillG
May I also point out that the USA can write legislation every which way it wants, but it does not have the authority to override national sovereignty? I know people in DC would desperately want that, but that's not how it works - they will still have to deploy the usual blackmail and (worst case) tit-for-tat tactics.
What that does change, however, is your ability to prosecute anyone for it: as it's legal in the US, the only way you can do it is on a local, national basis, and the US is unlikely to collaborate.
Honestly, I don't know what it is over there. I think the water poisoning problem is more widespread than they think..
