This is a book about how crime tends to happen in L.A and New York.
I think it is very silly that people learn martial arts to defend themselves from crime but they do not know anything about crime avoidance and how criminals operate, this book will help.
It describes how criminals approach their potential victims and interview them to see if they are a easy target. This section alone is worth the price of the book.
It describes how burglary, con games, sexual assaults, carjackings, muggings and various other street crimes tend to happen and offers advice on how to protect yourself. I especially found the advice on protecting your home from buglers and making your front door harder to smash down very interesting although I think they did leave out some important things.
This book is quite old (1994) and I think a bit of the information is dated e.g the info about finding payphones is no longer relevant with cell phones being common and I think it's even harder now that there are even less public payphones then when this book was written. Another example of dated info mentions that modern luxury cars are hard to steal but does not mention expensive car thieves have got round this problem by burgling people's houses to get the expensive car keys.
A interesting side note about this book is that the authors believe people became drug addicts because of horrid life experiences and environments which makes drug addiction a consequence of messed up countries, not the result of flawed characters. (Google "rat park" for studies on rats that suggest this could be correct)
A lot of the info in this book is L.A and New York specific but there is enough similarities in crime in the western world for this book to be useful for people living in England and I highly recommend this book.
