Re: "I find arrest is a proportionate response"
Wrong choice of words. He hasn't "locked himself up". He's hidden.
He's in hiding, and should get as much sympathy for "time served" as Ronnie Biggs did for all that time he was "forced" to spend in Brasil.
This can all be over any time he wants. That UN decision was both stupid and offensive, he was given full legal due-process at all times, and I'm glad the judge laughed it out of court.
