In my latest for @us.theconversation.com, I discuss limitations to local shelter availability, and why Section 8 is not a viable long-term solution.

Colorado has emergency domestic violence shelters in only half its counties, leaving survivors without safe housing options
A lack of shelters and affordable housing means survivors of domestic violence have few places to go.

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.

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.
