Sorry, but I have no problem extraditing people in foreign countries breaking US laws when they affect the US even if the country has no law against it.
So you don't mind that the US ignores the sovereignty of other world states?
Why we don't flip this around?
Have you ever posted anything pro-nazi (or anti-jewish), or a picture of a swastika on the Internet? (If you have you've broken several German and Israeli laws - let's get you on a plane to either country).
Has you wife/partner ever gone out alone without a male escort, and posted images of this online? Or even promoted anything against Islam online? (If so you've broken several Iranian laws, and she should be stoned).
Have you had an alcoholic drink in public or even been drunk? (If so, you've broken several laws of Qatar, UAE and Saudi Arabia).
Have you made disagreeable comments about Thailand and it's royal family? (If so you've broken several Thai laws).
Ever smoke pot or taken any other illegal drug and then posted the contents online? (If so you've broken laws in several SE Asian countries - some of which include the death penalty).
Ever taken a photo of a Italian government building, and posted it online? (You've just broken Italian law).
Have you carried a handgun in public? (If so, you better come to Australia and face court, as this is illegal here).
I guess my point is, is that we all done things at one time or another that are illegal in other countries, however all the states acknowledge and honour the sovereignty of other nations. (This is not a stab at the US or it's citizens - take this from a pure philosophically point of view), why should the US ignore sovereign matters that should be handled locally under the local laws of that nation? Why would a trial of a foreign national be better handled in the US, when the foreign national isn't even aware of the legal system in the US?
