EVERY immigrant who enters the US should have a transponder-type RFID chip implanted, if only to keep track of them as they disperse into the general population to the point they either overstay their visa, or they become involved in a crime of some sort, either as perpetrator or victim, and may thus be readily identified.
Just the thought of having a chip implanted should keep a LOT of would-be bad guys from ever entering this country.
Watch the ACLU types go overboard in condemning this “invasion of privacy”. There is NO presumption of privacy for wrongdoers. Don’t do wrong, and you can stay private.
Facial recognition software, becoming a standard practice in many venues, is “non-invasive” but the databases may be rather incomplete as of yet.
F NO.
