Usually when a book states on its cover "Exposes the secrets Scotland Yard never wanted revealed” or something similar, I find that it is just a ploy to get you to read/purchase it but here it really is true. Some of the secrets make me wonder how this is legal and I can certainly see why Scotland Yard would have an issue with it. Having read up a little on Mr MacLaughlin and being someone who does not readily trust institutions such as the police, I can also understand it from his point of view. The title "The Filth" should give you some idea of MacLaughlin's opinion of his fellow officers and as a fan of true crime, I knew I had to give this a go. It did not disappoint! Now I do realise that some of you may think he is merely using the pejorative term or slang for police in the UK but there's no doubt in my mind after reading this that this is in fact MacLaughlin's opinion of his ex-colleagues. There are sensational and really quite disturbing claims that officers from the Yard's Drugs Squad and the Regional Crime Squad stole drugs, paid phantom informants and fabricated evidence. That is just for starters. Some of it is shocking and I urge anyone who decides to read it to go in with a completely open mind. An excellent and exciting read. Whether the information is true or not is up for debate. What I do know is that the police are certainly not whiter than white, as they would have us believe. Highly recommended.
