One first step, is to ask the PD if they have the “national search” functionality enabled. As far as I can tell it’s a binary switch that allows data to be shared with other PDs in cooperation with ICE. I think it’s turned on by default and many PDs simply aren’t aware of exactly what it is.

See Denver for example: https://coloradonewsline.com/2025/08/06/immigration-denver-f...

This is low hanging fruit and if you can get them to shut that off it’s a quick win. Mine had already shut it off. Denver turned it off after above news story got traction.
