A while ago, in spring 2017, I filed FOIA requests with U-M and the AAPD to retrieve a crash report and two dashcam videos of the March 16, 2017 incident in which an AAPD vehicle collided with a light post on the Diag while pursuing a suspect.

The crash report is available here or via A2Docs, and dashcam videos are embedded below:
