I think the leaving of evidence up and about is a great way to instill fear and confusion, creating angst in the population.
A simple synopsis would be, create so much chaos and disruption, let"society" crumble and run amok to the point where government will step in and say "hey, things are getting of hand, we need to take more more control here", which seems to be what the government is aiming to do. But creating such a strong divide among people is a great way to keep people at each other's throats and distract everyone as well.
This is all scripted so perfectly that it looks like a mess, but it's a controlled demolition. Like the WEF guy called it, "the great reset".
