“…The growth of §287(g) was decisively shaped by Attorney General Ashcroft’s contentious exploration, made public in 2005, about whether or not state and local police had the “inherent authority” to police immigration violations, absent formal delegation through programs such as §287(g) (Office of Legal Counsel, 2002). Ultimately, the Department of Homeland Security (DHS) shied away from this argument, but the upshot was that §287(g) was widely normalized, and embraced, as a more modest and legally less suspect way to get state and local police involved in immigration enforcement (see overview in Valdez, Coleman, & Akbar, 2017). By 2007, §287(g) had spread across the U.S. south and southeast and morphed into an expansive suite of state and local policing practices aimed at general immigration violations: Through the so-called “task force” version of §287(g), state and local police were empowered to ask about immigration status during routine policing, and without making an arrest on criminal grounds; and through the “jail model” version of the program, state and local police were tasked with interviewing individuals booked into custody about their immigration status, which could include a so-called “immigration alien query,” via telephone.…”
