About ten years ago, I remember an article about a special tattoo ink that was encased in laser-sensitive capsules. When irradiated, the capsules burst and the ink was absorbed virtually completely. The thing that outraged me was that they were having a hard time selling it, as tattoo "artists" were refusing to have their "creations" be removed at the user's behest. Most artists were even refusing to tell their customers that removable ink was an option. Since criminals don't have resumes, tattoos used to be their signaling mechanisms. As suburban kids began to make that signalling useless, a few years ago I read that criminals had moved on to painful eyelid tattoos. A quick Google search shows that didn't slow the posers down very much. I wonder how criminals signal how badass they are these days?
