There is so much corruption and dishonest dealings by the various agents of the state in all these miscarriages of justice, they can literally do what the hell they want to, it means nothing to these criminals who work within the criminal justice system if they have to falsify evidence along the way, they do things wrong and often get promoted, they think when they lie, it is a form of truth, if they dodge the evidence up, plant incriminating evidence on someone, or put it somewhere so it can be found, its called great detective work, if they re-write notes in dodgy pocketbooks, it almost guarantees them a contract with a book publisher, they tamper with witness statements, and in many cases they don't even know they've made a statement, because one of thier dodgy colleagues has made a statement for them, they hide and conceal themselves in dodgy surveillance vans to allow them to introduce dodgy identification / recognition evidence, even though the van they were supposed to be in, was at the time they were supposed to be in it, was parked up back at the police compound over 11 miles away - and none of them ever get convicted of anything by the dodgy criminal justice system, in fact in most cases they get promoted, what a joke this criminal justice lark is, your having a laugh, are'nt you...
