UK courts are quite troublesome and have proven so already. They have stopped the extradition for a child rapist because he could get life in the US...
He cannot be extradited from Sweden if he is there due to extradition from the UK without going through the UK's courts as well.
Do you seriously need reminding of the thousands upon thousands of incidents where governments all over the world have been proven to have committed all kinds of awful acts, but only years later after administrations change and documents become unclassified? The idea that we shouldn't even suspect government wrong-doing until solid evidence materializes is ridiculous.
Suspicions are fine when there's actual evidence, otherwise they are baseless conspiracy theories. Do you have any?
