I might have done better to find a more recent edition of this. My edition (written in I think about 1993 or 1994) and what it says about computers is quaintly out-of-date. It tells you how to write code to construct your own text-only computer database to compare different crimes, and speculates that one day in the far distant future there might be some kind of statewide or nationwide system that could monitor criminals and sort out suspects that match the profile.
