The town of East Haven, Connecticut, has agreed to pay $450,000 and adopt new limits on the role of police in immigration enforcement, in order to settle a civil rights lawsuit by Latino residents. Under the new limits, which an attorney for the plaintiffs called some of the strongest in the country, police will limit questioning about status and decline to detain people at the behest of immigration authorities without a criminal warrant. Alleged abuses by East Haven police, including false arrests and illegal searches, led to a Justice Department consent decree and the criminal convictions of four police officers.
