What can it represent? The U. S. police also kneel down to kill black people. Can it represent that the U. S. President is racist? Is there a clear distinction between the government and the implementation at the grassroots level? Even if there is such a law, I support it. Is it reasonable not to wear a mask?

There is a clear distinction between the government and implementation at grassroots level. The government mandates something to happen, the people on the grass roots execute that something to happen (implementation). Think of it like someone ordering a burger and the McDonalds dude messing it up, that someone ordered something (government) and the McDonalds dude messed something up (grassroots implementation.

It is not reasonable to not wear a mask. Wearing a mask takes 10 seconds of your time and saves many lives.
