>After two hitmen were arrested for killing a man, the FBI wanted to prove that they'd been hired by a family going through a child custody dispute. The FBI arranged to trick the family into believing that they were being blackmailed for their involvement - and then sat back to see the reaction. While texts and phone calls were reasonably easy for the FBI to access, in-person meetings in two restaurants were a different matter. But the court authorised the use of Wave Sciences’ algorithm, meaning that the audio went from being inadmissible to a pivotal piece of evidence.

While the technology and the way it is marketed now is cool and everything, it feels like the most interesting part of the article is this FBI investigation. Too bad it's only mentioned in these few sentences with no further details.
