Now, please don't abandon me on account of the flippancy. Because I sincerely believe that if you were to read one or two of these books, you'll be a better cop for it. And if you haven't the time or inclination for reading, then it might hearten you to know some are available on audio books.
And since this is a patrol column, I decided to include books that if they don't help you become a better cop may at least help you in some other aspect of your life, which will inevitably improve the prospects of your being a better cop.
"The Art of Deception" by Nicholas Capaldi
Simple without being simplistic, Capaldi's book is an excellent primer on logic. Now, if you're like me, you may not be a fan of logic, at least as it might be communicated in the sterile confines of a classroom. But Capaldi's book dispenses with the algebraic notations and cuts to the chase in laying out what logic is all about. And therein lies its appeal.
In easy to read prose, Capaldi illustrates how people fall prey to fallacious contentions and illogical conclusions. By recognizing the errors of their ways, officers can conduct better interviews, better investigations, and write reports that anticipate others' anticipations (i.e., defense lawyers' arguments). Capaldi's book can also help you do a better job of testifying on the stand.
