Computer hackers and the perpetrators of securities fraud are having quite a moment, aren't they? This week, the man behind the largest computer hacking case in U.S. history, Albert Gonzalez, was taken into custody and he now finds himself in a (computer-less) jail cell in Brooklyn facing charges he made off with 135 million credit and debit card numbers. And we certainly don't have to tell you that 2009 as been a banner year for fraudsters armed with all any number of financial schemes designed to line their pockets and empty your own. But can you tell the difference between a computer hacker and fraudster just by looking at them? And could you differentiate a rogue techie and evil financial genius from a garden variety pedophile? It's harder than it looks! Below you'll find a sampling of mugshots of men who have been arrested for one of the three crimes. It's up to you to tell them apart. Good luck!
