The proposed bill, titled the "Defense Against Criminal Illegals Act," aims to establish enhanced penalties for illegal aliens who commit serious felonies involving violence. It defines serious felonies to include offenses such as murder, aggravated assault, and rape, among others. If an individual is convicted of such a felony while illegally present in the United States, they will face increased penalties, which vary based on the classification of the felony. Additionally, the bill mandates that prosecuting attorneys notify defendants of these enhanced penalties and stipulates that individuals convicted under this section will not be eligible for early release on parole or other forms of supervised release for the enhanced portion of their sentence.

Furthermore, the bill expands the state's ban on sanctuary policies to include counties and unincorporated areas, ensuring that local governments cannot adopt policies that limit cooperation with federal immigration authorities. It also allows sheriff's offices and the Division of Correction to participate in the Warrant Service Officer Program, which enables state and local law enforcement to execute administrative warrants under federal immigration law. The bill outlines the process for local law enforcement to apply for participation in this program and establishes consequences for local governments that violate the sanctuary policy prohibition, including ineligibility for state-administered funds or grants.
