social upheaval following Floyd's murder in 2020, he argues, disrupted a generation-long decline in crime rates built in part on the data-driven, targeted policing strategies that emerged in the 1990s

I look into this off and on. It's likely the reduction is for a major part due to the reductions in lead in gasoline. The pandemic did interrupt the decline with some chaos and then it resumed the decline. So we do benefit from the EPA stuff.

Our attempts at crime prevention by police work have not been shown to work. For instance, right now, how many of you think illegal aliens are reporting crimes? How about those here legally but not fully citizens? How about Temporary status? Etc., Etc., Etc.

And...
"The national murder solution rate (known by the FBI as the "clearance rate") has experienced a steady, long-term decline, dropping from over 90% in the 1960s to an all-time low of roughly 52% in 2022, before rebounding to between 58% and 66.5% in recent years."

Less murders, a section of the populace not incentivized to cooperate with the police, and a lower clearance rate. In the PI the murder clearance rate was ~22% before Duterte and dropped further to ~17% under Duterte, murder rate before was 9.5 per 100k and jumped to 11.5 under Duterte, ostensibly due to police killings.

Nobody is charged for Good or Pretti, and it looks like nobody will be. Pretti was flat out murdered on camera.
