I don't know anything whatsoever about the background of this at all. Those people sound like kooks to be honest. The police officers go extremely far to do what they have to do as politely as possible. In an actual authoritarian state - like Russia where these people come from - the police would not talk like this to anyone. They'd barge in, shout orders, point guns at people, cuff everyone and take them away.

Also, this has nothing to do with Covid-19. The two people are being taken to an examination in a mental hospital.

By the way, this takes place in Canada, not the US.
