Sounds like the RFID tags some schools are giving kids here to prevent terrorists or kidnappers some such bullshite.
You know, this whole "terrorist" problem just really isn't all that hard to solve at all.. All you have to do is just arrest these 5 individuals:
(*) Henry Kissinger;
(*) Zbigniew Brzezinski;
(*) David Rockefeller;
(*) George Bush Senior;
(*) Oliver North;
and your rate of international "terrorism" is going to plummet by about 98%..
