I've always found it hilarious, that most crims seem to have tattoos, which can readily help to ID them. Dumb or what !
If they plant spyware onto a system that can read all the files (i.e. pictures of tattoos), wouldn't it be 1000x easier to just get the IP address of the computer and trace it that way? Or barring that (coffee shop WiFi or whatever), seeing log-ins to Facebook, personally identifiable email, Skype, e-commerce, etc etc? Or face pics (face identification tech is old news)? It seems like the use case of this technology is extremely narrow, a scenario where the only identifiable data on a computer is a tattoo seems incredibly unlikely. That being said, compartmentalization of identities is a prudent measure that many here already know to do, I guess many criminals aren't very smart though (even DPR...). Maybe it's wise to grab some rando's tattoo pics from Instagram or wherever and put them all over your hard drive in order to point investigators in the wrong direction, lol.
Yes and then when they are in prison they get more tattoos just to make sure when they get out the cops have no doubt about who they are every time they see them lol.
One time, long ago and very wasted, I watched some guy tattoo another guy, using a knife and hash ashes
