Boosters of surveillance technology argue that it can make cities safer, improve traffic, speed up airport and stadium lines, make workers more productive and safeguard valuable company property.

The big picture: People are willing to be watched in certain cases. Most people trust the police to use facial recognition responsibly, according to a new Pew Research survey, but the majority don't trust tech companies or advertisers to do the same.

Details: Police say facial recognition accelerates investigations, stripping away some human biases and shortcomings.

  • NYPD commissioner James O'Neill wrote in a New York Times op-ed in June that facial recognition matches led to nearly 1,000 arrests in 2018.
  • The volume of important digital evidence has exploded so fast that it's "quickly outpacing our ability to deal with it," says Jim Burch, president of the National Police Foundation.
  • But, but, but: Historically, surveillance hasn't clearly prevented or deterred terrorism and crimes. There’s no good data yet about emerging methods.

Companies, too, monitor employees' computers and phones to make sure they're not about to spill the beans to competitors or the press.

  • Or, by checking up on workers, they claim to "optimize productivity" and deliver projects more quickly.
  • For instance, Upwork, a company that helps clients find freelancers for code and design jobs, uses screen recording technology to "provide proof of work."

CEO confidence skyrockets on expectations of layoffs and wage cuts

U.S. consumers remain uncertain about the economic environment but CEOs are feeling incredibly confident, the latest survey from the Conference Board shows.

Why it matters: Confidence among chief executives jumped 19 points from its last reading in July, rising above the 50-point threshold that reflects more positive than negative responses for the first time since 2018.

Louisville officer: "Breonna Taylor would be alive" if we had served no-knock warrant

Sgt. Jonathan Mattingly, the Louisville officer who led the botched police raid that caused the death of Breonna Taylor, said the No. 1 thing he wishes he had done differently is either served a "no-knock" warrant or given five to 10 seconds before entering the apartment: "Breonna Taylor would be alive, 100 percent."

Driving the news: Mattingly, who spoke to ABC News and Louisville's Courier Journal for his public interview, was shot in the leg in the initial moments of the March 13 raid. Mattingly did not face any charges after Kentucky Attorney General Daniel Cameron said he and another officer were "justified" in returning fire to protect themselves against Taylor's boyfriend.
