Now putting myself in the shoes of the protesters: seeing the same destruction, destroying of properties, cars and businesses, I'll call it a day because this is no longer a protest. I'd go back home and wait for this to be taken care of and join a civilized protest once this has been taken care of. A civilized country should be able to hold a civilized protest. And having spent most of my life in eastern Europe, you can say I know a thing or two about protests. Last large protest I was a part of was in ~2013 irrc and the aftermath was very different. The night after each of those protests, everything was spotless clean, people thew all their garbage in the bins, nothing broken or destroyed. People were coming with their children and pets and being completely comfortable with it. There was a completely unrelated incident of a gas explosion at a Chinese restaurant, which burned a nearby shop. People gathered donations fo the shop owner to recover. Incidents with police? Practically none during ~3 months of daily protest. And we are talking eastern Europe - the police officers are anything but the nicest people on the planet.

The protests started out peaceful but became less peaceful when the police showed up and tear gassed innocent crowds. There's people literally getting arrested for practicing their right to assemble and right to freedom of speech.
You are confusing the idea of collectivism (in which each individual is responsible for the welfare of the members of the group, and is expected to sacrifice to some extent—different variations on collectivism vary on the extent—their own welfare for the common good) with the concept of collective punishment (a widely recognized violation of human rights and, in the context of armed conflict, a war crime, in which members of a group are punished for mere shared membership in a group which contains wrongdoers, without any evidence of collaboration in or support for the wrongdoing.)
They are not equivalent.
No, it's not. Participation in a mass protest may be motivated by collectivist ideals, or it can be motivated by the individualist ideal that it is better to discourage a government course of action that could in the future be of grave danger to you individually, and that the immediate risk of participation in the protest is less than the long-term risk of the policy being protested against.
People of ideologized strictly and emphatically opposed to collectivism engage in mass protests.

The legitimate task of the police is to protect the rights of all (innocent, suspect, and even, except to the extent specifically and legitimately deprived due to their guilt, the guilty). There is no circumstances when participation in a gross abuse of human rights is within the scope of their legitimate task.
