As reported in the Philadelphia Inquirer and the Daily News, the Philadelphia Police Department has announced that it will adopt key changes in its interrogation practices.  After years of complaints that homicide detectives held suspects and witnesses against their will in order to secure signed statements, new procedures will place important limits on the detention of suspects and ensure that witnesses are aware that they are free to leave at any time.  Additionally, following the lead of many jurisdictions around the country, the Department will require the video recording of all interrogations in homicide cases.  The change in practices follow the work of KRMF partner David Rudovsky, who presented the Department with several cases involving witnesses who were held by homicide detectives against their will for lengthy periods of time.
