Julia Preston of the New York Times offers "Report Faults Training of Local Officers in Immigration Enforcement Program" (nytimes.com/2010/04/03/us/03immig.html), referring to the 287g program:

State and local police officers who enforce federal immigration laws are not adequately screened, trained or supervised, and the civil rights of the immigrants they deal with are not consistently protected, according to a report released Friday by the Department of Homeland Security inspector general.

The report by the department’s internal watchdog was a sweeping review of a program run by Immigration and Customs Enforcement. Through agreements signed with about 60 county and state police forces, the program allows local officers to question immigrants about their legal status and detain them for deportation.

The inspector general’s report describes the program as haphazardly administered, with local agencies detaining and prosecuting immigrants with little oversight from federal agents and significant inconsistencies from place to place.

You can read the report - and the entirely predictable responses from the American Civil Liberties Union, the Immigration Policy Center, and the National Immigration Law Center - at blogs.ilw.com/gregsiskind/2010/04/dhs-report-slams-287g-program.html

Per Dan Stein of FAIR (link):

Since taking office, the Obama administration has consistently undermined immigration enforcement. An DHS inspector general report focused on 287(g) is the latest attempt to provide critics of 287(g) with ammunition to halt or eliminate the program. Among the report recommendations include more "civil-right" data recording and changing "performance measures that do not focus on aliens who pose a threat to public safety or are a danger to the community." In essence, the IG report is critical of ICE for not moving fast enough to implement the revised 287(g) guidelines that put "catch-and-release" back in place for non-violent criminal aliens. The legislative history and original intent of the 287(g) program is clear - it was meant to encompass all illegal aliens, and that was how the program was run until the Obama administration. Since then, the administration has attempted to remake the program into a watered-down jail screening program and to reduce its effectiveness at finding and deporting illegal aliens regardless of the severity of their crimes.
