Kind of ridiculous to think everyone turns into murderous idiots as soon as government goes away. Sure there are going to be bad seeds but just be ready for them. Kind of funny how you think.
In times of a disruption of civil society, I'll go with Selco's views that you don't really know people the way you thought you did. I don't walk around all paranoid, but there are a fair amount of people that don't do harm to others because they'd get in trouble, not because of morality.
