How science may just end up killing crime

1983. Forensic scientist Steve Cordiner's first homicide.

He arrives in a Lower Hutt house to find a woman dead, her head bashed in, blood everywhere.

Cordiner opens a plastic sewing box for a "notebook, my pens, my rulers, some chemicals to do some presumptive tests of blood, and that was about it".

He uses those to study "the patterns of blood stains on the wall, to give an opinion as to the minimum number of blows that must have occurred, from where the blood was and how it was distributed".

Fake America great again

Guess what? I just got hold of some embarrassing video footage of Texas senator Ted Cruz singing and gyrating to Tina Turner. His political enemies will have great fun showing it during the midterms. Donald Trump will call him “Dancin’ Ted.”

Okay, I’ll admit it—I created the video myself. But here’s the troubling thing: making it required very little video-editing skill. I downloaded and configured software that uses machine learning to perform a convincing digital face-swap. The resulting video, known as a deepfake, shows Cruz’s distinctively droopy eyes stitched onto the features of actor Paul Rudd doing lip-sync karaoke. It isn’t perfect—there’s something a little off—but it might fool some people.

There Is No Tech Solution to Deepfakes

Every day, Google Alerts sends me an email rounding up all the recent articles that mention the keyword "deepfake." The stories oscillate between suggesting deepfakes could trigger war and covering Hollywood’s latest quirky use of face-swapping technology. It’s a media whiplash that fits right in with the rest of 2018, but this coverage frequently misses what we should actually fear most: A culture where people are fooled en masse into believing something that isn’t real, reinforced by a video of something that never happened.

In the nine months since Motherboard found a guy going by the username “deepfakes” posting face-swapped, algorithmically-generated porn on Reddit, the rest of the world rushed straight for the literal nuclear option: if nerds on the internet can create fake videos of Gal Gadot having sex, then they can also create fake videos of Barack Obama, Donald Trump, and Kim Jong Un that will somehow start an international incident that leads to nuclear war. The political implications of fake videos are so potentially dangerous that the US government is funding research to automatically detect them.
