The future is a funny thing. Nobody knows what the future holds or how it will change. Crime and crime fighting are an even bigger mystery. Take for example the art of crime fighting twenty years ago and it today. While forensics and DNA have come a long way to definitively prove a persons guilt or innocence, the number of violent crimes has gone up and the dynamics in how such crimes are committed has also changed over that time. Put this altogether and what that means for the future and you have yourself a pretty original idea for a science fiction story. So when I saw The Mammoth Book of Future Cops I picked it up and started reading.
