The water from the wrecked Nova Kakhovka dam, which is inundating land near the Dnieper river, is sweeping away landmines. It can leave them anywhere in the inundated land.

*Hundreds of thousands of mines and debris are flowing into towns downstream, while lack of water upstream will hit food production*, due to the destruction of the Nova Kakhovka dam.

Russia seems to have destroyed Ukraine's Nova Kakhovka hydroelectric dam. Substantial areas of land will be flooded; Ukraine is hurrying to evacuate people.

Various minority groups in England and Wales got a disproportionate fractions of the fines for breaking Covid-19 lockdown rules.

This study strongly suggests that many thugs acted based on bias, but it cannot conclusively prove that, because it does not control for other variables — such as the actions of people who were fined.

For instance, the study found that poor people got a high proportion of the fines. Was this because they had to travel by walking and been seen by thugs, while wealthier people went by car? That would be systemic bias rather than individual prejudice.

Contrast this with the Massachusetts courts' study that showed blacks tended to get bigger sentences than whites for comparable crimes in comparable circumstances. By controlling for the other things that can vary between groups, it pretty much proved that bias was at work in the legal system itself. That showed that the legal system is inescapably to blame for the injustice.
