Well, I dunno.
I went to the original source, and it appears to have happened in Lincoln, Nebraska, in the middle of the night.
The two vehicles (the guy with the woman who bit the officer was towing one behind them) had no license plates. The guy, with a 15-year suspended licensee, has a Germanic name common in Nebraska; the woman who bit the officer has a Hispanic last name.
They could be blue-staters, though.
It wouldn't surprise me at all.
