It is a FACT that the streets of the once beautiful city of San Francisco are littered with human faeces, needles and homeless camps and that muggings, car break-ins and assaults are astronomical. A regular annual medical practitioner's convention just cancelled because of these conditions. So...how did this happen?
Human beings are not wonderful, caring, respectful creatures by nature. They are greedy, violent, lustful and slothful by nature. Regardless of how laws of behaviour and morality were instituted, history demonstrates that it is necessary to teach these laws to children at an early age, demand that they be obeyed, and execute discipline when they are not. Childhood training isn't enough. The same principles must be instituted in adult society as well. The point is a society will deteriorate into ugliness and depravity if the rule of law is not enforced.
So obviously what we are witnessing in SF is a breakdown in the system of law and order. Therefore the blame for this disaster falls on the shoulders of whoever is prime administrator of law and order in San Francisco. Who would that be? Why..the mayor, of course.
