AUBURN — Next time the police show up at your door, you might not know it’s them knocking thanks to an Auburn resident.

On Monday night, the Auburn Police Department posted on their Facebook page a photo of a door with a note that read “Nock hard but not like you the police.”

To which the Auburn PD responded: “Apparently we have a tell tale knock?? Might be time to change our knocking techniques to keep them guessing?”
