1) How many people died as a result of McKinnon's actions? How many died in Lockerbie as a result of the bomb? Do the words "sense of proportion" mean anything to you?
2) American law allows them to go into another country, commit a criminal act (kidnapping) and take someone back to America to be tried. The perpetrators of the kidnapping are not tried for any offence and the courts don't care *how* the suspect was brought there.
3) The current extradition treaty just requires *suspicion* from the US, but *proof* from the UK. Not exactly equitable, is it?
4) How would you like to be offered a "deal" where you're told "come and be tried in our country and plead guilty and we'll let you serve your sentence in your own country, refuse and if we get our hands on you we'll throw away the key"? Whatever happened to the concept of a fair trial or the presumption of innocence?
Now I'm going to downvote you.
