Lol, protect and serve.
In slang terms to serve is to kick someones behind.
Is that what it means when that is printed on the individual cars?
It is quite catchy "To Protect and Serve".

(Edit)
Ok now I have watched the video.
Do these "Officers" even think about the millions of cameras that are around?
Does it even matter?
Do we know how the prisoner is doing?
Is this "Officer" still employed?
