HARRISBURG, PA (WSKG) – Pennsylvania’s state police force is reviewing its interactions with the federal immigration and customs enforcement, in the wake of a series of investigative reports questioning the legality of troopers using traffic stops to detain people in the country illegally. It’s still not clear how law enforcement agency will change their procedures, or when. An investigation by ProPublica and the Philadelphia Inquirer found the Philadelphia Immigration and Customs Enforcement office–which oversees Pennsylvania, Delaware, and West Virginia–arrests more undocumented immigrants without criminal convictions than any other ICE office in the country. Unlike police in many other states, Pennsylvania state troopers don’t have official partnerships with ICE –nor do they have limits on questioning people about their legal status. It’s largely up to individual troopers to decide whether to question people about their immigration status or contact ICE agents.
