Pinal County Sheriff Ross Teeple testified before the Senate Judiciary Subcommittee on Crime and Counterterrorism on Sept. 23, 2026.

The Pinal County sheriff was on Capitol Hill on Wednesday to testify about automatic license plate readers, known as ALPRs, made by the company Flock and others.

Citing privacy concerns, Sheriff Ross Teeple recently opted not to renew a contract for ALPRs.

Now he’s calling on members of the Senate Subcommittee on Crime and Terrorism to help regulate the tech.

“We must establish clear statutory boundaries for automatic license plate readers. We cannot wait for a future Supreme Court ruling to correct AI overreach. We must protect the Fourth Amendment today,” Teeple said.

Teeple’s August move was followed by a flurry of local police agencies reporting internal misuse and several cities cancelling contracts for automatic license plate readers.

Amid growing concern of Fourth Amendment violations and law enforcement misuse, nearly a dozen Arizona communities have decided to end their use of automated license plate readers, or ALPRs.
