For ICE there are likely hotlines for your region and its probably the most important type of cop watch rn. I sadly know the most about the PNW so hopefully someone from your area or city can recommend local orgs.
Typically you want to get any photos of ICE you can, license plates+types & color of vehicles, number of ice agents, types of uniforms etc are extremely important and a name for the person abducted if you're able.
