Records show that a federal grand jury subpoenaed the Chicago Police Department for these same reports on Aug. 28.
Bringing charges against the officers for their statements could be difficult, however. Under federal case law, statements the officers were compelled to make as part of the police department's internal investigation cannot be used against them in any criminal prosecution.
The reports state investigators viewed the video and found them consistent with officers' accounts. The reports also note the 911 call after the shooting and radio transmissions from the scene "were consistent with the statements of the police officers."
The city has released information — including the video — in dribs and drabs, prolonging the scandal around McDonald's shooting. It was only after the video's release, in fact, that Emanuel fired Police Superintendent Garry McCarthy, saying McCarthy had lost the public trust.
