I don’t remember much about this movie in color but for some reason, there was a lady who seemed nice and along the way she was carrying her husband’s head who can still talk in a bag.

One day, the cops spot her on a bridge I think and one of them faints after seeing the head in a bag, which eventually leads to her arrest for supposed murder.

Also, she had a young nephew who helped bury his uncle’s head somewhere while trying to figure out how to get his aunt out of prison. Also, he recounts the time he met an important black man in a flashback who was later shot in front of him by a dirty, racial cop (who is later arrested after the boy’s aunt is released from prison).
