Fox News report on San Francisco technology ban

Critics also question the damage the ban could cause to law enforcement. Speaking with Fox News, Jeff Talbot of the Washington County Sheriff's Office in Oregon pointed out that facial recognition technology has helped his team catch several suspects, including a convicted thief.

"We want to be on the forefront of fighting crime and keeping our community safe," he said. "We recognize that criminals will keep committing crimes and they will always be trying to find ways to stay ahead of the law enforcement investigations. And this is just another tool."
