Comment Riot Police Will Tag you (Score 1) 238
While this whole topic is pretty funny, there is a military/riot police application for this and in the works. They target rioters with an RFID gun/projective and tag you. Later they block off an area and the paddy wagon comes by with an RFID scanner and scoop up those unfortunate folks who have been tagged. Scope with digital image matched with the RFID tag number and you are toast.
With some of the tags you'll be picking them out of your flesh with a knife to get them out....
