The only section I needed to read was "causation". Essentially, there's no evidence that this is a causal effect of attractiveness on sentencing, and there are many alternative explanations available.
So do an RCT please.

Whenever I see correlation assumed to be causation I like to wonder why they excluded causation in the other direction. In this case, maybe sentencing someone heavily is hard on their looks, and we know once you go to jail you’re likely to reoffend, and that continues, until you have the correlation you observe, perhaps?
