The fallacy of the brilliant criminal mind (or how geeks help catch the bad guys)

I've known several police officers in my life.  Even today, one of my best friends is a police officer.  One of the things they've all said is that criminals, as a group, are pretty stupid, or at least make really stupid decisions.  Otherwise, they wouldn't be criminals.  Stories abound of dumb criminals doing dumb things and getting caught, but this article from Mental Floss really drives the point home.  Those of us who enjoy technology love opportunities to use what we know, especially when it involves righting a wrong.  Never underestimate the wrath and cunning of a geek crime victim!
