@Melonlity -- I have a major problem with international laws. I live in the United States and only this nation has jurisdiction over me. I don't want some lawmaker in Australia to determine whether something I do is legal or not.
It is easy to say that international law is great when dealing with something everyone agrees on such as computer hacking. But that would set a nasty precedent through which we would be subject to other international laws. What if there is an international law against smoking, driving over 40 miles per hour, building cars that get terrible gas mileage, etc.?
What works in one nation doesn't necessarily work in the United States or other nations. People who advocate international law seem to forget that. Those national differences are reason enough for us to not violate the sovereignty of countries.
