In the southern regions of Mexico, there’s a little town called Oaxaca that did a grand experiment in law enforcement. Faced with the silent output of hundreds of security cameras in public spaces, they hired deaf officers to read lips and look for clues for solving and preventing crime. And it worked. These amazing people have found thieves, murderers, buried bodies, and they’ve even saved precious human life from horrible kidnappings. The deaf officers are called the Angels of Silence. Their story is true, something so remarkable in my eyes that it inspired the fictional tale you are about to read. There’s even a little HPC in there for you.
