A recent update from the Immigration Policy Center released a fact sheet about the 287(g) program, in which DHS/ICE deputizes state and local law enforcement officers to perform the functions of federal immigration agents. These officers are not federal employees but are local law enforcement employees, but have access to federal immigration databases and may interrogate and arrest non-citizens believed to have violated immigration laws and issue detainers to keep them in custody.
Some jurisdictions were found to violate the program and they terminated the agreement, such as Sheriff Joe Arpaio's Maricopa County in Arizona and Alamance county in North Carolina. ICE is conducting a nationwide review to determine which agreements should be renewed in 2013. It costs localities money they do not have and arrest very few real criminal. The main people arrested under the program are offenders who are not a threat to public safety or individual with no criminal record or minor traffic violations.
Most jurisdiction wither 287(g) programs have a higher rate of Latino populations and these program divest necessary police resources from dealing with serious crimes into enforcing immigration laws.
