Recommendation to Inform and Improve the Chicago Police Department’s Rule 47

December 31, 2025

Summary

The Public Safety section of the City of Chicago Office of Inspector General (OIG) recommends measures to inform and improve investigations conducted by the Chicago Police Department’s (CPD) Bureau of Internal Affairs (BIA) into alleged violations of CPD’s Rule 47.

Executive Summary

CPD’s Rules and Regulations includes its Rules of Conduct, which serve to inform its members of conduct prohibited by the Department. Rule 47 prohibits members from “[a]ssociating or fraternizing with any person known to have been convicted of any felony or misdemeanor, either State or Federal, excluding traffic and municipal ordinance violations.” During its regular review of closed disciplinary investigations conducted by BIA, OIG identified inconsistencies across investigations in BIA’s analyses of the relationship between the accused CPD member and the individual convicted of a felony.
