The problem with this argument is that it assumes that one killing implies anarchy and and discarding of the system. It does not. Chances are, most reasonable people believe there should be a chain of justice with courts, laws, and investigations.

Someone has turned to vigilante justice here not because they believe that the courts are useless, but because they believe that this is such an extreme case that courts would not have worked in this case.

What I believe people fear is not the rise of anarchy due to one killing, but a fundamental shift in attitudes of the ordinary people in response to the unreasonable rise of the power structure. This threatens not order but the very power structure itself, which implies that a lot of people who benefit from injustice will suddenly be at risk of losing those benefits (money).
