When police team up with ICE, it ripples into classrooms [latimes.com]

Half of all Americans now reside in a “sanctuary” jurisdiction where state or local political leaders have committed to supporting refugees and undocumented residents by declining to cooperate with Immigration and Customs Enforcement in certain ways. But other communities have moved in the opposite direction. These “reverse sanctuary” communities have adopted partnerships with ICE that effectively deputize local police to enforce federal immigration laws.

The Trump administration has overseen a dramatic increase in these federal-local partnerships, which are called “287(g) programs” after a 1996 section of the Immigration and Nationality Act. There are 78 active agreements, nearly two-thirds of which were adopted in the short time since Trump took office.

When the Department of Homeland Security approves an application from a local police agency, ICE trains local law enforcement officers to identify and arrest undocumented residents while, in theory, respecting 4th Amendment rights against unreasonable search and seizure. Under the “jail enforcement” model, the police only screen those who’ve already been booked into jail. Under the “task force” approach, local police incorporate immigration enforcement into all their day-to-day policing activities.
