I did fingerprints from a digital photo in 2012 maybe earlier. Old mate was holding up drugs to be photographed. Bit of contrast, blew it up, sent it to fingerprint bureau and what would you know, we had those prints on file. Not the crime of the century and not absolute proof, but a damn good start for a case from a simple post on socials. More useful than most intel/hearsay that ends up in crimestoppers or similar channels.
