I'm not making an assertion though. The onus is on the person presenting the argument to show that the stats support his conclusion. I did not state that the graph is definitely showing a statistical anomaly (from a cursory inspection it does not even appear to be that anomalous). It just doesn't show what the OP thinks it does (and the author of the article even stated as such).And it so happens to be my opinion that the discrepancy in penalties it is in fact a largely a coincidence
