Delaware Cop on Duty Sings 'Shake It Off': Taylor Swift Loves the Video

We've all been guilty of rocking out and lip-syncing to a catchy tune at least once in our life. It doesn't matter who you are. When the right tune pops out at just the right moment, you can't help but belt out and put on your best moves. Even if you're a police officer sitting alone in the car -- or at least seemingly alone.

Case in point, the Dover Police Department in Delaware posted a video on YouTube and Facebook showcasing the energetic and infectious moves of a 19-year veteran officer Master Cpl. Jeff Davis shaking off to Taylor Swift's hit song "Shake It Off."
