You just never know what a police car's dash camera is going to catch...

Case in point: check out 19-year veteran officer Jeff Davis hilariously lip syncing and head bobbing along with Taylor Swift's hit song "Shake It Off."

The awesome video already has more than 14 million views on YouTube.

Apparently approving of Officer Davis' interpretation of her song, Taylor Swift re-tweeted the video and complimented the cop's "sass."

A spokesman for the Dover, Delaware Police Department confirmed that the video was staged. Officer Davis' killer moves, however, are all real.
