Dover Police Dashboard Cam Confessional Shake It Off gif
Adam Rifkin stashed this in Po Po!
That's one happy cop :) I like how he gets all serious when he responds to people, then back to his singing and car dancing once apparently out of their sight.
I like that too -- I think it makes the video for me. Happy guy!
