What would happen? Well, for a start, Teresa May would be starting a prison sentence for breaking UK law under which the deportation has been denied because we are signed into legal agreements with the ECHR.
Let's leave all the invective aside for a moment, and just consider what is going on here.
This man has not been accused, tried, or convicted of a crime here, but has spent seven years in detention while extradition hearings are completed.
The courts have decided that there is not sufficient guarentee that evidence gained under torture would not be used against him - hence no extradition, because the UK will not support a lehal process that permits this type of evidence.
You can wail and gnash and foam all you like, but the law is the law, and it works for everyone, not just those whom people are pereceived as being OK, but those whose rhetoric and attitude is utterly abhorent.
Because if the law does not protect everyone, it protects no-one, so it has to stand, however much we may not like what it means for us.
So be grateful that our laws are strong enough not to be bent to suit the howling of citizens who know little of the facts - because a lot is kept from us for national security reasons - we only hear a little bit of what is actually going on here.
Do you really imagine for one second that if the British government was able to legally and without repercussions worldwide extradite this horrible man, it would not have done so by now? We, and they are bound by the law, like it or not.
