From "Law and Order" to "CSI," not to mention real life, investigators have used fingerprints as the gold standard for linking criminals to a crime.

Well, it wouldn’t be good evidence on its own at court, but can very well nudge an investigation in a right direction. And anyway, it’s a first step, done with little resources and ablimited dataset for training. And at least for me, it’sbthe first time I hear something like this is possible at all. Others said that tools to the same effect were around for quite a while, but I haven’t seen anyone providing sources, especially some that would give quantification of its capabilites.
