Are you saying the 36-hour hike in the murder rate *was* an anomaly and that it *was* legitimate not to take it into account? In any case, it's been my impression that the study design used quite sophisticated statistical methods (such as time-series analysis) for evaluating trends over a five-year period so as to try to isolate variations that had no explanation other than that of the presence of the experimental group. (This was rarely reflected in media accounts, however.) What kind of study design would you have used that would have avoided these sorts of questions?
