The purpose of this legislation, known as "Sarah's Law," is to enhance the enforcement of immigration laws by requiring U.S. Immigration and Customs Enforcement (ICE) to detain certain non-citizens who have been charged with serious crimes that resulted in death or significant injury to others. The goal is to ensure that individuals who pose a threat to public safety are not released back into communities while their legal matters are pending. Key provisions of the law include mandatory detention for non-citizens charged with crimes that lead to death or serious bodily injury.
