The reason I didn't mention that was because I very much doubt that many people, that don't know how to avoid these files, will know what location the results come from just by looking at an IP. Or know the laws for that specific country. Also if they are using Proxy to connect through it will not be easy to decide where an IP originates. (For the normal Limewire user that is. For the autorities it is easier.)

It should be a thing for the authorities to decide, if they have any chance of pursuing these sickos or not. The fight against KP is multinational and they work together on it as far as I know.
