2005: DHS and DOJ began “Operation Streamline

A joint initiative which adopted a “zero tolerance” approach that included the criminal prosecution of all unauthorized border-crossings. Rather than immigration cases being heard individually, they were instead tried in large groups — of up to 70 people at a time. Each defendant would have about 90 seconds to plead their case, and if convicted, serve anywhere from 30 days to two years in prison or in a detention center.  

2003: The Homeland Security Act divided the Immigration and Naturalization Service, or INS, into three separate entities

U.S. Citizenship and Immigration Services, or USCIS; U.S. Immigration and Customs Enforcement, or ICE; and U.S. Customs and Border Protection, or CBP — and placed them under the jurisdiction of the newly created Department of Homeland Security, or DHS. Prior to this, INS had been under the Department of Labor.

2001: After the Sept. 11 terrorist attack killed almost 3,000 people in New York City, the government focused on national security more than even before in its history

The Bush Administration passed the Patriot Act, which among many other provisions, greatly increased the power of the Attorney General to detain immigrants for longer periods of time – in some cases, indefinitely.

1983: The Reagan administration formed its Mass Immigration Emergency Plan

Which significantly expanded U.S. immigration detention by requiring that 10,000 immigration detention beds be located and ready for use at any given time. That same year, the Corrections Corporation of America, or CCA, is formed in Nashville, Tennessee, becoming the world’s first private prison company. Upon its creation, it was immediately awarded a contract by the U.S. Department of Justice, or DOJ.
