I never thought they were guilty either. Someone told police the two of them like drones and live 5 miles from airport. Job done and perps arrested. They were banged up more than 24 hours, should be some compo there surely but i am not totally sure of the rules.
I personally was once, a long time ago, arrested for a robbery at a solicitors office in Braintree, Essex. They kept me for 24 hours but they knew after just a few hours that they had the wrong person. (I just happened to be in the wrong place at the wrong time). They still waited until the 24 hours had elapsed until they released me. Oh, and I can still remember some of the comments from a couple of them like "nice car, how did you afford that" and the custody sergeant saying that anyone arrested is done so for a good reason and there was always "no smoke without fire".
You won't find me trusting cops nowadays I'm afraid.
