Synopsis
Malloy tries to prove Sgt. MacDonald's innocence when Mac accidentally hits and kills a jaywalker while driving his police cruiser. Every witness on the sidewalk claims she was in the crosswalk, and the burglary suspect MacDonald is transporting is unmotivated to testify on his behalf. The truth proves to be far more complicated than the officers realized.
