Those of us who do not live in New Zealand can easily (or relatively) file motions to have lawyers, judges, politicians families etc, cut off due to our claims that they have downloaded copyrighted material.
Since we don't live in New Zealand, even 'if' we are incorrect and they didn't... they have no recourse. However, the families of New Zealand politicians et al are just as 'guilty' as the next person-- we all know that, just as their kids do.
The only question will be how to find their IP addresses... but it will be a hop, skip, and a jump before NOBODY in NZ has internet... how do you think the internet providers (and the population) will feel about the law then?
