Interesting material on (e.g.) -- abrasions, Bertillon, bite marks, cadaveric spasms, Chechen hostages, chloroform, Arthur Conan Doyle, drowning, Dunblane, ethnic groups, fingerprints, genetics, ground-penetrating radar, haemoglobin, Hitler diaries, identikit, J F Kennedy, Libyan Embassy, maggots, Georgi Markov, mass graves, narcotics, 9/11 [five pages], nitrogen, Occam, polygraphs, quicklime, radiocarbon dating, Rasputin, ricin, Rwanda, security in bomb blast areas, sexual differences, Shipman, steganograhpy (hiding messages in long computer files), taphonomy, teeth, vitreous humor, Waco (edited down from a long list).
What interested me also was the philosophical aspects here. We all know philosophers never say anything useful on knowledge - they are paid to be evasive. But in forensic investigation, theories and observations and witness statements all contribute to the final result. There are two pages on 'expecting the unexpected', trying not to be biased by preconceptions. Interesting comparison of crossword clues with real life - all the bits have to fall into place, and it may be as unexpected and yet as satisfactory as the solution to a 'cryptic' crossword. This of course is somewhat idealised - in practice there are investigations as with Dr Kelly, or JFK, or Diana Spencer where truth takes second (or third..) place.
