An audit by the Department of Homeland Security’s Inspector General found that Immigration and Customs Enforcement (ICE) is facing a variety of challenges, particularly with implementing the Known or Suspected Terrorist Encounter Protocol (KSTEP). KSTEP allows a myriad of law enforcement and intelligence agencies to coordinate and streamline the “protocol for identifying and processing aliens who are known or suspected terrorists.”
ICE can only screen immigrants while they are in custody. As of June 2017, just 33,701 of 2.4 million—about 1.4 percent—of all immigrants actively monitored by ICE and Immigration Enforcement and Removal Operations (ERO) were subject to KSTEP screening for connections to known or suspected terrorists. The problem is exacerbated by the fact that “some law enforcement agencies will not honor ICE immigration detainer requests,” thereby preventing ICE Enforcement and Removal Operations (ERO) from taking custody of criminal aliens for KSTEP screening.
From January 2014 through May 2017, approximately 675 jurisdictions nationwide refused to honor more than 29,269 ICE immigration detainer requests. When a state or local law enforcement agency declines to transfer custody of a removable criminal alien to ICE, the released alien may put the public and ERO personnel at risk and it then requires significantly more resources to bring the individual into ICE custody.
California denied 11 ICE detainer requests, the majority for immigrants convicted of violent crimes, between January and February 2017, taking the cake for most detainer requests declined, 3,348, between 2015 and 2017. So-called “Sanctuary Cities,” having been specifically designed to limit or prohibit immigration authorities, were the worst offenders.
