You've made a huge assumption there, and characterisation, and that's exactly the problem. I and many others are not sympathetic or uncritical of the action at all. I'm just critical of not having debate about the differences between this and other actions and removing the debate.
I'd say, yes, it was a civilian airliner. It affects more people. However to do it to a private jet too shows precedent to abandon international norms. Nobody being arrested is merely because Snowdon wasn't aboard. If he was, he'd have been arrested. And the diversion of any plane to an airspace where the arrest of someone on board can take place by a foreign power, is ultimately what is the issue here isn't it? And there are enough obvious parallels that at least we have the discussion, not just remove the discussion forthwith.
