More crime ahead?

Abortion rates have fallen to the lowest number in years.  This drop may be due to a more prevalent use of birth control pills, despite George Bush's attempts to not allow schools to teach their students about their options.  

This news may not be all good.  Steven Levitt was able to link more abortions to less crime, so we may be facing a crime wave in 15 or so years, when the children who "could have / should have" been aborted reach the age in which they can commit crimes.  If you are unfamiliar with this study, I highly recommend reading Freakonomics.
