U.S. Immigration and Customs Enforcement (ICE) has used Secure Communities to identify 780,000 illegal immigrants since 2008 but only deported a small fraction of them.

Immigrants, City Fear Divide Over Status Checks

Nationally, the program has identified about 780,000 illegal immigrants since 2008, according to ICE data. Of that number, 162,940 have been deported. The largest share of those deportations, about 30 percent, were convicted of a crime punishable by less than one year in jail. A further 27 percent were convicted of aggravated or multiple felonies.

ICE has a failure rate of 80%!  What an accomplishment. Perhaps this is why ICE wants to replace 287(g) with Secure Communities.

Immigration Enforcement Program To Be Shut Down

WASHINGTON – The Obama administration is starting to shut down a program that deputized local police officers to act as immigration agents.

Immigration and Customs Enforcement officials have trained local officers around the country to act as their agencies' immigration officers. Working either in jails or in the field, the officers can check the immigration status of suspects and place immigration holds on them.

The program, known as 287(g), reached its peak under President George W. Bush, when 60 local agencies signed contracts with ICE to implement it. But that trend slowed significantly under President Obama— only eight agencies have signed up since he took office, and none has done so since August 2010.

Which also helps explain the decline in deportation cases filed by ICE.  And ICE's moral problem.
