“A new TRAC study, Detention of Criminal Aliens: What Has Congress Bought?, based on the analysis of hundreds of thousands of records obtained from Immigration and Customs Enforcement (ICE) and an examination of its budget, explores the changes in ICE’s enforcement record since the beginning of FY 2005, when Congress drastically increased the agency’s funding for the apprehension and detention of criminal aliens. The record shows that while overall funding for ICE grew by 67 percent, appropriated dollars provided for the agency’s office of Detention and Removal Operations (DRO) more than doubled, increasing by 104 percent. The data further show that from FY 2005 to FY 2009 the overall number of detainees surged — growing by 64 percent — but the number of individuals categorized as criminal detainees barely budged.”
