Our picture of the day is a simple one: Cops policing cops.

Chinese Business News published photos from a Weibo user in Xi’an, Shaanxi, which showed a parking ticket plastered on the side window of a police cruiser on Shangpiao Road.

We’re not sure why these photos tickle our fancy; but, it’s nice to see the police being held accountable for at least some of their infractions.
