Friend of mine just got back from Madrid. Spain is 91% vaxxed. Everyone wears masks inside and outside. You get a computer thing to carry around that has your passport number, name, and a bunch of other data. Everytime you go into a store, a restaurant, a museum, whatever, you show the computer thing and they scan it......They can thus track you down if the need arises. The populations is very compliant.
How would that work here? Idiots would say it is to much of an invasion of privacy and so forth.
