UNITED STATES (AP)— Taser developer Axon said this week it is working to build drones armed with the electric stunning weapons that could fly in schools and “help prevent the next Uvalde, Sandy Hook, or Columbine.” But its own technology advisers quickly panned the idea as a dangerous fantasy.

The publicly traded company, which sells Tasers and police body cameras, floated the idea of a new police drone product last year to its artificial intelligence ethics board, a group of well-respected experts in technology, policing and privacy.

Some of them expressed reservations about weaponising drones in over-policed communities of color. But they were not expecting Axon’s Thursday announcement that it wants to send those Taser-equipped drones into classrooms to prevent mass shootings by immobilising an intruding gunman.

In an interview with The Associated Press, Axon founder and CEO Rick Smith said he felt compelled to make the idea public after the mass shooting at an Uvalde, Texas elementary school, saying he was “catastrophically disappointed” in the response by police who didn’t move in to kill the suspect for more than an hour.

But he stressed Friday that no product had been launched and any potential launch would be down the road. The idea, he felt, needed to be shared now because of the public conversation about effective ways for police to safely confront attackers and how schools can increase safety.

“This is an idea that should get into the public’s consciousness while our minds are open to it and I felt if I wait another six months, the world is going to change and people are going to forget this pain and we’re going to see a shift in sentiments where people are going to focus a lot more on what could go wrong, rather than the pain of this problem we need to solve,” he said.

Axon’s stock price rose with the news. But the announcement angered members of the ethics board, some of whom are now likely to quit in protest.

“This particular idea is crackpot,” said Barry Friedman, a New York University law professor who sits on the Axon AI Ethics Board. “Drones can’t fly through closed doors. The physical properties of the universe still hold. So unless you have a drone in every single classroom in America, which seems insane, the idea just isn’t going to work.”

Friedman said it was a “dangerous and fantastical idea” that went far beyond the proposal for a Taser-equipped police drone that board members — some of them former or current police officials — had been debating in recent months.

“We begged the company not to do it,” Friedman said of the company’s announcement. “It was unnecessary and shameful.”

The product idea had been kicked around at Axon since at least 2019 and the company has been working to try to figure out whether a drone with a Taser was even a feasible idea. Over the last year, the company created computer-generated art renderings to mock up a product design and conducted an internal test to see if Taser darts — which transmit an immobilising electric jolt — could be fired from a flying drone, Smith said. He added that he had discussed the possibility of developing such a product with the ethics board.
