Saudi 'Killer Chip' Implant Would Track, Eliminate Undesirables
The basic model would consist of a tiny GPS transceiver placed in a capsule and inserted under a person's skin, so that authorities could track him easily.
Model B would have an extra function — a dose of cyanide to remotely kill the wearer without muss or fuss if authorities deemed he'd become a public threat.
The inventor said the chip could be used to track terrorists, criminals, fugitives, illegal immigrants, political dissidents, domestic servants and foreigners overstaying their visas.
