This came to my attention today:
Woman yells ‘you can’t arrest me’ as she’s arrested during cafe vaccine checks
I'm not going to comment on the insanity of the situation, but my first thought was - there are 4 or 5 police officers arresting this person! Like, Australia must have tons of money available to pay so much police to go arrest a woman because she didn't show a vaccine passport. One would think there are no real criminals there. If 5 police officers can afford to take the time (and car fuel) to take this woman into custody as if she was a serious threat to society, even though she doesn't react violently and doesn't seem to be carrying a weapon, that must mean the country has loads of resources, or they don't have any real crime to deal with, right? Lucky people...
I don't think it'd work in the US. The police aren't supposed to search you/request ID unless you are suspected of committing a crime.
