If you read this article and have a halfway decent model of the world in your head, you will realize that police entrapment was the proximate cause of this real, talented artist low on his money becoming a counterfeiter: i.e. they made him do it, and he wouldn't have done it without them, and a judge released him early on probation for this reason (from the article).
But the damage was done. Still without any money, this genuine artist (who had "refused to do two Warhol copies, including forged signatures", always signing his own name instead on homage pieces) now had a criminal skill that had no other applications.
The fact is most people here have had a time in their life when they had unhoned skills (e.g. software/hardware hacking) that, if they only landed the right internship, would become very valuable. When the police are the proximate cause to creating this "lucky" internship (lucky in that the guy had 0 experience with it, or even interest for that matter) to create skills that have only a criminal market [1], something is very wrong.
It would be great if Freakonomics covered entrapment some time, as it's very insidious - on the surface it seeems that if you do it you "would have done it anyway", but this example shows pretty obviously that this isn't true in any form whatsoever.
[1] EDIT: or not even a criminal market, as the case may be:
"The problem was, Kuhl and his partners couldn’t make a deal with anyone. It wasn’t for lack of trying—a sale brokered by a criminal-minded former cop fell through, and another transaction with a supposed buyer in Majorca fizzled. That was when Becker and his colleagues decided to help things along by providing an attractive buyer themselves."
