ICE Enforcement and Removal Operations (ERO) faces challenges in implementing the Known or Suspected Terrorist Encounter Protocol (KSTEP) screening process, which is used to identify aliens who may be known or suspected terrorists. Although ERO uses KSTEP to screen all aliens who are in ICE custody, ERO policy does not require continued screening of the approximately 2.37 million aliens when released and under ICE supervision. We sampled and tested 40 of 142 ERO case files of detained aliens identified as known or suspected terrorists during fiscal years 2013–15. All 40 files had at least one instance of noncompliance with KSTEP policy, generating greater concerns regarding the population of aliens screened and determined to have no connections to terrorism.
