Pressing prisons and jails to violate the 4th Amendment isn’t part of ICE’s job description

One of the tools in the federal government’s immigration enforcement kit is the detainer — a written request by Immigration and Customs Enforcement agents to a state prison or local jail to hold a person suspected of being in the country illegally for up to 48 hours beyond his or her scheduled release. ICE makes the requests to give immigration agents time to go pick up the person for possible deportation.
