Does Down Economy Increase Crime?

Article here from the Wall Street Journal questioning whether a perceived rise in crime is a result of a faltering economy.

The general take:

"By and large, the studies show that lousy job markets -- particularly for young or unskilled men -- are linked to more thefts. But the connection isn't so plain with violent crimes like murder and rape. That bolsters the theory of a more rational criminal: When the economy flags, people inclined to crime opt for dishonest income; they don't start shooting people."
