Immigration and Customs Enforcement (ICE) wrongfully and repeatedly targeted and arrested American citizens for years, with as many as 1,480 U.S. citizens being arrested since 2012. This is according to an investigation conducted by the Los Angeles Times (Link here http://www.latimes.com/local/lanow/la-me-citizens-ice-20180427-htmlstory.html).
The report goes on to highlight how hundreds of U.S. citizens were forced to prove their identities in immigration courts, sometimes while spending months or years in detention. ICE makes around 100,000 arrests a year, but the high number of wrongful arrests is still troubling, especially given the fact that ICE policy requires a legal review within 48 hours if someone in custody claims to be an American citizen.
An ICE spokesman responded to this report by saying immigration agents only make arrests with probable cause and they take seriously any claim that a detainee is a U.S. citizen. One of the causes of the wrongful arrests was the use of inaccurate and incomplete databases, both electronic and paper.
VERDICT: There should be no reason that, in 2018, there it should take more than 48 hours to verify the citizenship of a detainee. The Trump administration has been requesting more funding to continue to increase strict immigration enforcement; however, any new funding given to ICE should immediately go to decreasing the number of current detainees.
