A Tempe police official told The Times that his agency opted out of the unusual program. But Jennifer Lynch, an attorney with the Electronic Frontier Foundation, said the offer was concerning.

"We have no way of tracking what's going on in the private realm," she said. "All we have is the publicity statements these companies put out."

Law enforcement agencies have denied public records requests for license plate data, and private data collectors are not subject to such records requests.

"A lot of times," Lynch said, "they even have a clause that says law enforcement agencies aren't allowed to talk about their products without talking to the company first."
