Here we see fairly conclusive evidence that the practice of falsifying crime stats has become MORE pervasive (approximately twice as much, from roughly 25% to over 50%) since 2000, at least in NYC.
Previously we blogged on the same topic in Milwaukee and we alluded to such as a possibility for why the ratio of aggravated assault to homicide seems to have stopped improving.
It looks like that possibility (medicine for trauma continues to improve but the denominator is falsified moreso than in the past) is strongly supported. The study referred to in the story is a very useful one---we expect a certain amount of fudging on crime stats, this gives us a real indicator of how the amount of such falsifying has changed over time.
