I'm sure American Rattlesnake are exploring this kind of issue that surely occurs around the nation all the time. This story from our local NBC affiliate:
The Director of Immigration and Customs Enforcement has written Cook County Board President Toni Preckwinkle, blasting the County’s decision to ignore immigration detainers at Cook County Jail, warning her that the County is likely in violation of federal law.
ICE Director John Morton suggested the County’s decision to release accused criminals back into the community without informing immigration, was a danger to the community.
"The ordinance disrupts the federal government’s efforts to remove deportable criminal offenders from the country, and instead allows for their release back into the community," Morton wrote. "The release of so many of these individuals to the streets of Cook County is deeply troubling, and directly undermines public safety."
