We may not be there yet but hardly a week goes by without a cold case being solved in Europe (don't know about the US). There are judges, for example in France, who are now forcing cases to be re-opened due to greatly advanced and also greatly lowered costs for DNA testing. So cases where DNA was collected decades ago is now usable. A case has been solved a few days ago (forgot which one it was) but the one that impressed me the most was a cold case where the killer was a serial killer and... a cop. Once, 20 years after the last crime or so, a letter was sent to all the cops that could have been in Paris (they suspected a cop was the killer) at that time was sent to ask them for a DNA sample, that cop, now retired cop due to his age, committed suicide. He knew it was "gg". Bad times for bad guys who committed crimes a long time ago: at any point now the cold case may be solved. These cold cases being solved also make it to the news, frontpage: constantly reminding those who got away with their crime that they cannot sleep tight. It may be sci-fi, today, to use DNA to predict a face and then to run facial recognition on it but... It's not sci-fi to use new science discoveries to solve cold cases. And I'm very happy that motherfuckers are getting caught.
