His personnel file shows Ross left the sheriff's department in 2004. He resigned instead of being terminated after failing to show up to testify in court on a day when he had dozens of criminal cases on the docket.

He also missed a grand jury appearance, according to the file.

On top of all that, Ross lied about having insurance when he rear-ended someone in his pickup truck, the file shows.

Video of the DUI checkpoint in Rutherford County, already viewed millions of times online, was recorded by a member of the Libertarian Party and raises questions about drivers' rights at checkpoints.

"It's nearing 3 million YouTube hits. Just with my name being on the press releases, my email and phone is just being bombarded," said Axl David, communications director for the Libertarian Party of Tennessee.
