'Let's track paedos with chip implants' - top cop fails tech test / The Register, 16 Jul 2006

"Britain's most senior policeman has, according to a Sunday Times report, suggested that surgically implanted chips could be used in order to track the movements of paedophiles and dangerous sex offenders. "If we are prepared to track cars, why don’t we track people? You could put surgical chips into those of the most dangerous sex offenders who are are willing to be controlled," said Ken Jones, president of the Association of Chief Police Officers. Should we explain that the chip you're talking about would have around about the same capabilities as the RFID chip that's going into ICAO standard passports? That this is the kind of technology you're probably going to insist can only be read in close proximity to a reading device? That if you tried really hard (and we're sure people will), you could read it at maybe 10, maybe 30 metres? That satellites are actually quite far away? Or that what GPS does is it tell a reading device on the ground where it is, which would only help paedophiles if they were lost - if it's going to help you then you need to insert another bit of technology (A mobile phone maybe? Where would you stick that?) that would pass the location over to you."
