Philadelphia bans police officers from asking anyone about their immigration status, and when officers inadvertently learn of someone's status, it is only entered into a police report if that person is suspected of a crime. The city also does not honor Immigrations and Customs Enforcement requests to detain undocumented inmates past their release dates — unless ICE produces a criminal warrant. Officials were heartened, Hitt said, to see the new restrictions did not mention detainer requests.
