Yeah it was on Radiolab. Amazing tech. Terrifying, amazing tech.
Hard to criticise it’s use in war zones, it seems incredibly invasive in a civillian setting.
The Juarez use case was amazing though, for those who haven’t seen it, the prosecutor (I thought she was a police officer?) was driving to work, a car pulled in front and blocked her path, another car boxed her in, cartel gunmen leaped out and executed her in the street, then drove away.
After the crime was reported, they were able to identify the vehicles, see where they had come from and where they went, they identified a senior member of the cartel with this process.
It is compelling stuff and I can see how law enforcement would be easily seduced by it.
The implications for privacy when this tech is applied to civilians without oversight are truly dystopian though.
