Flock Safety's AI-powered license plate cameras have become a big issue in US election campaigns.

Candidates from both parties are attacking the technology.

It works in 6,000 communities across nearly every state.

Critics call it unconstitutional mass surveillance.

Police say it is a vital tool for fighting crime.

In Wisconsin, the governor's race has centered on the cameras.

Democratic nominee David Crowley said he would limit their use and protect privacy.

His Republican opponent, Tom Tiffany, promised to pause state funding.

He also said he would create a task force on safeguards.

In Pennsylvania, both Governor Josh Shapiro and his opponent Stacy Garrity said they support a ban.

Other races show similar divides.

A Michigan congressional candidate called the cameras "un-American."

A Florida Senate candidate sells anti-Flock merchandise.

In Rhode Island, Governor Dan McKee paused new camera installations before the primary.

President Donald Trump said his administration is studying the issue.

Flock Safety defended its technology.

It said the cameras helped solve about one million crimes.

They also helped reunite roughly 10,000 missing people with their families.

Police groups backed the cameras too.

They warned that removing them would be a mistake.

However, some voters and activists see them as a threat to civil liberties.

Experts say surveillance technology will likely remain a major political topic.
