I think many USA people like Iranian people have micro implants in ears and mouth or throat.
Several countries gov and private organization , install it inside human.
KSA-islamic-fundamental organization and Islamic Mafia of Iran ,from 1990s, had understood these smart-dust technologies exist, therefor they had paid for complicity.
I think installing these implants that some of them only a simple analog electronic device, now be easy. These can install during, working in army , school , office, only need, victim be unconscious by some spray or drug.
