Saying Trump is "weaponizing" these systems ignores that they were already much-used weapons, only targeting ppl w/o political power. DOJ's blessing of Rene Good's shooting is based on precedents from cops getting a pass in >1,000 such cases/year. If this is authoritarianism, maybe that was, too.
Mapping Police Violence
Law enforcement agencies across the country are failing to provide us with even basic information about the lives they take. So we collect the data ourselves.

There are several evidence-based explanations for the crime spike and decline. I summarize them here, and explain why some fit the data better than others: johnkroman.substack.com/p/explaining...

It’s interesting that there seems to have been some inflation in the estimates too: it was 18,000, then 18,500, now I see 19,000. It’s totally plausible there is an increase, but, you’d think we’d *know* this!
