If you have to read this book for a course, then you have my sympathy and, for a couple of quid, you can have my copy; if you don't have to read this book, save your time and money.
So that you may save the said time and money, this is what the book is about: David Cantor and how brilliant he is; how it should be possible to catch serial killers by mapping the locations of their kills and body dumps; David Cantor's personal prejudices; how, if serial killers kill and dump near their homes, it should be possible to find where they live; David Cantor's other writings and how brilliant they are; if serial killers don't kill and dump near their homes, how it should be possible to find where they live; David Cantor's invaluable help (as he tells it) to the rather dim-witted police; if serial killers travel long distances to kill and dump, how it should be possible to find where they don't live; David Cantor's contempt for databases, particularly police databases; David Cantor's brilliance...
Of course geographical mapping has a place in offender profiling. I suspect one or two other people have discovered this before David Cantor. It doesn't take a prolix and somewhat over-jargoned piece of writing like this to say how and why geographical mapping has a place in offender profiling.
This book is also irritating in that it is not particularly well proofed, which adds to the irritation caused by the constant intrusion of David Cantor into what there is of seasoned argument and narrative.
If I've saved you the time and money, my purchase and reading of this book hasn't been a complete waste of life.
