Are we seeing the first signs of civil society breaking down? The veneer of law and order is very thin. When it goes, it will go fast IMO.
If you are going to have civil society break down, you need to threaten peoples sense of security.
Make it hard for them to secure food.
Make water uncertain.
Make being secure in their homes uncertain.
We are an incredibly rich society, and we are very, very far from those situations.
I believe the tendency to law and order in American society is much more durable than you do. If local law enforcement becomes unreliable, we will self-organize militias or vigilance committees.
It is what we have always done.
