Unfortunately it's taken losing Sarah to such a horrific crime to ask such a question. But what are we supposed to do. Someone arrests you off duty and you don't know whether u can trust them due to this case. What would you do? Ring 999 and say I'm being arrested by so and so but I don't know if he's on duty or if he's dodgy please can you log it somewhere. I just want to know if I'm definitely being taken to the police station I feel unsafe. There should be some sort of law. But what could you do? You've got no chance. No chance of safety. It's scary.
