Today the Times reports
on the NYPD's Real Time Crime Center, which contains databases on, among other things, tattoos, body art often being among a person's more distinguishing characteristics and thus a useful way of matching descriptions to prior records. (They also have databases for birthmarks, silly walks and skin conditions—so if any of you are taken into custody during a breakout, be sure to mention that your complexion is usually clearer, you've just been a little stressed lately.) Text-based tattoos are especially easy to match to a person; tribal tattoos, being abstract, are more difficult.
The ability of police to track down a person based upon a pattern inked permanently into his or her skin is an important component of the NYPD's ever more data-based policing. It is also almost certainly a pilot program of the coming one-world government, which plans to implant microchips and barcodes in all "citizens." The mark of the beast!
