Florida law enforcement agencies’ cooperation with federal immigration officials is causing concerns among family members and immigrants’ rights advocates that people will disappear into county jail systems. Miami-Dade officials said this week they are committed to transparency and will continue to follow state laws regarding the release of information about inmates. But one section of an agreement with U.S. Immigration and Customs Enforcement designates all records and information created under the agreement as federal records. Some say ICE would have the final say on what information is made public, including whether a person is even in custody. ICE said any allegations that detainees are not provided due process are false.
