Happy to talk w/Stateline about clearance rates.
Clearance rates are a fundamentally important metric for how well our public safety system is working by focusing our attention on solving crimes. Solving crimes w/certainty & swiftness is also proven to prevent future crime.

State officials say they're hopeful this will lead to more data-driven policies and decision-making within the justice system — and improved public safety in Washington.

Yet, crime remains a top concern for New Yorkers, despite fewer major crimes. This appears to be driven by complaints fueled by lower level incidents. gothamist.com/news/nyc-hom... via @gothamist.com

I hear from many police leaders how their federal partners working with them on violent and major crimes have been pulled off these task forces and sent to civil immigration enforcement.
There is a serious tradeoff risk being made here - especially as many local depts still struggle with staffing.

This is my periodic plea, when you are doing your political assessments post-failure, it’s a fool’s errand to think we just need to “message better.” You have to contend with the fact that certain policies are not popular if not simply wrong.

One thing I’ll say about the “democracy protests” that I’ve seen happen now in 3 different states: they’re filled with people who seem to be 60 years old and up. Not your typical demographic for protests.
