However, that is not to say that judicial prejudice can never be detected. In certain cases, when that prejudice is present and the model uncertainty is narrow enough, we can. See example for the case of disparities against Black offenders.

We do not know what is the right set of controls, so the only honest answer is to find a way reflect that model uncertainty. This involves accepting that the true extent of judicial prejudice is unknowable. See model uncertainty in disparities in sentence length vs Hispanics in the US Federal Court.

First time in Barcelona. I can confirm all the nice things that I've heard about it, but more than the nreathtakimg architecture or the weather, I am in complete awe about how easy and pleasant is to get by around here. These people deserve all the praise they are getting.

Yes, but suspended sentences are not used to calculate the increase in custodial sentence length, which for indictable sentences has been huge

On early releases emergency decisions like the 'Standard Determinate Sentence 40%' have been adopted recently.

This is a question I need to get right (I cannot say "Avoid using GenAI at all to eliminate any risks of mistakes") in order to complete the compulsory training on GenAI required at work.
I'm not anti Ai, I find it useful for tasks like coding and proofreading, but this feels like forcing it.

When neighbourhoods are affected by 'heavy traffic' perceptions of vandalism, burglary and theft grow from 6% to 9%, and that is most likely an underestimate.

Worth noting the widely different trends followed by different offence groups. In cases like drugs or criminal damage most of the increase in sentence severity is driven by an equivalent increase in the seriousness of crimes processed (probably due to attrition at the arrest/ prosecution stages)

This is such a cool paper. See #homicide rates as they are reported by each country (first column) compared to how they end up when we adjust them according to counting rules known to be applied inconsistently (third column). Tldr: cross-country crime comparisons can be quite noisy.
