ROUGH JUSTICE comes from that section of True Crime books which include telling the story of particular cases, and then analysing aspects of those cases.
As with all these sorts of books whether or not it will work for the reader depends on a number of highly subjective elements - whether you agree with the issues raised by the author (either that they exist or they are issues); whether you agree with the outcome or the methodology of that analysis; and whether or not you like or dislike either the tone of book, the raising of the case, the author or any combination of these and/or any other elements you want to raise.
Makes this sort of book a tricky read for a lot of people and you'd have to be silly not to think that True Crime, in particular, is an easy path for either author or reader.
What I appreciated in this book in particular is that the cases that were raised were raised, that the issues that were highlighted were highlighted, and the analysis that was undertaken was voiced. No idea if I agree or disagree or even came up with my own conclusions in the main. But the justice system in this country has to be robust enough to stand up to scrutiny, which is part of the reason that I read these sorts of books - regardless of the cases, the author, the issues or the period of time that has passed.
