I'm a bit confused now. Can the US police break into a house if you aren't wearing a mask or can't they? I understood that the police did that in the mentioned case because of illegal gatherings at home, no matter if they wore masks or not.
Here in Germany, one's home has special protection. You can basically do at home whatever the hell you like, as long as it's not going to the outside or abusing anybody. For example, you probably know that it's not allowed here to do nazi things in public, like waving swastika flage, doing the Hitler salute, singing the Horst Wessel song etc., but you are free to do all of that at home. Likewise, the members of a household don't have to wear masks at home. Gatherings of too many people who don't belong to the household is illegal though and the police can (and did) dissolve such gatherings.
And that idea doesn't bother you? You went outside without a chin diaper, therefore it's ok to have the gestapo...I mean...police barge into your home and arrest you? Are you sure there's nothing at all you find remotely disturbing about that image?
You are right, the choice of action has to match the deed. It sounds a bit outrageous if the police decides to break into you home for that. Did they really do that? It would be enough to ring the bell and if you don't open, put a letter into the post box, informing you that a fine of $250 or so is due for that.
We have a few measures here as well that don't find my consent. For example, some states here disallowed the sale of fireworks and its burning of fireworks New Year because the expected amount of additional work for hospitals and ambulances would hamper the treatment of Covid cases. I think that the enormous amount of fireworks here at that time is silly and dumb (and many of the dumb people here are burning the heck of a lot of it) and I would appreciate less of that, but people have rights like freedom of choice. There's a limit somewhere, of course, but disallowing it altogether went too far in my opinion. Yes, Covid needs a few restrictions on what we regard as granted otherwise, but there's a limit.
