Sex offender satellite suffers serious flaws

| | Comments (1)

gps_satellite_650.jpgA satellite system devoted to tracking sex offenders recently released from prison suffered from too many bugs to be realistically implemented. The original idea was to use four satellites as a GPS to keep more accurate tabs on known sex offenders by way of an attached radio-transmitting ankle tag.

"...a pilot found that the signal emitted from the tracking devices could be blocked by clouds, buildings or leaves. It was also lost underground and on some trains. The Ministry of Justice has decided to focus instead on lie detectors as a means of controlling paedophiles released on parole. The U-turn will leave ministers facing accusations that they have failed to address the threat that communities face from 30,000 registered sex offenders."
