The chief and the commissioner are, in many cities, the same position: the head of the department. In smaller cities that could be simply the sheriff. In some cities, like New York City (or in this case, Gotham), they have both. While the Chief is a uniformed, sworn in member of the police force, the Commissioner is appointed by the mayor (or elected, depending on what Batman comic you're reading). Also, the Commissioner is the Chief's superior.

Can I quote you on that?
