When I silently wish for the extradition effort to fail, I'm not backing him. I really just want to see a sovereign allied anglophone nation tell the US to see that its jurisdictional claims stop at the 12 NM limit, and to please mind its own business. I don't want to see US playing at world police, except for crimes heinous enough that every nation should be combating them wherever they may occur, like war crimes, terrorism, international financial fraud, and hijackings of international shipping vessels.
Why should Dotcom get so much effort? What risk does he pose to US citizens to justify transporting him out of NZ? Whatever that may be, the risk of allowing the US to assert intellectual property jurisdiction over the whole Internet is far worse.
I'd like Dotcom to eventually get comeuppance, but not in a way that establishes an undesirable precedent.
