I finished reading Michael Mansfield's Memoirs of a Radical Lawyer yesterday. It is absolutely enthralling, though admittedly I've always been interested in the justice system and the way it works. I don't always agree with his politics but I love his enthusiasm for his cases and his ability to admit when he made a mistake and things didn't turn out how he expected.
He covers many of the famous cases of the last 30 or 40 years including the Jill Dando murder, the Marchioness disaster, the inquest into Princess Diana's death, the Bloody Sunday enquiry and various miscarriages of justice. There are well thought out arguments for retaining jury trials for as many offences as possible and for not relying totally on DNA evidence.
The book is written in an engaging conversational style and Michael Mansfield unravels complicated subjects so that they are comprehensible to all. This is an excellent book whether you are interested in the law or in our life and times.
