"The recent increase in violent crime defies easy explanation, and many hypotheses have been put forward for debate. In this brief, we propose that the rise in violent offending and the explosion in the sales of iPods and other portable media devices is more than coincidental. We propose that, over the past two years, America may have experienced an iCrime wave."
