The Trouble With Trusting AI to Interpret Police Body-Cam Video

Axon is promising its AI will be able to describe events recorded in body-cam video, but we’re skeptical

On 17 July 2014, a group of New York City police officers approached 43-year-old Eric Garner on a Staten Island sidewalk and attempted to arrest him—for allegedly selling cigarettes illegally. When Garner pulled free, one officer wrapped an arm around Garner’s neck, forced him to the ground, and pressed his face into the sidewalk. Garner, who had asthma and heart disease, repeatedly pleaded, “I can’t breathe,” before passing out. Unconscious, he was transported to a hospital, where he was pronounced dead an hour later. The medical examiner later ruled Garner’s death a homicide.

This tragedy drew national attention thanks to a cellphone video, which revealed in shocking detail the grossly excessive use of force that Garner was subjected to at the hands of police. Garner’s killing, and those of other unarmed black citizens by police, sparked protests throughout the United States.

Early 2020s 3D printing meets late 1920s mechanical television.

Before flat screens, before even cathode-ray tubes, people watched television programs at home thanks to the Nipkow disk. Ninety years ago in places like England and Germany, broadcasters transmitted to commercially produced black-and-white electromechanical television sets, such as the Baird Televisor, that used these disks to produce moving images. This early programming established many of the formats we take for granted today, such as variety shows and outside broadcasts.

The size and weight of a Nipkow disk makes a display with more than a few dozen scan lines impracticable (in stark contrast to modern screens with thousands of lines). But when a mechanical TV is fed a moving image, the result is surprisingly watchable. And Nipkow displays are fascinating in their simplicity—no high voltages or complex matrices. So I wondered: What was the easiest way to build such a display that would produce a good quality image?

One of the biggest challenges in a world-building competition that asked teams to imagine a positive future with superintelligent AI: Make it plausible.

The Future of Life Institute, a nonprofit that focuses on existential threats to humanity, organized the contest and is offering a hefty prize purse of up to US $140,000, to be divided among multiple winners. Last week FLI announced the 20 finalists from 144 entries, and the group will declare the winners on 15 June.
