re: When the police stop coming to work, then what?

That won’t happen, what will happen is the nature of law-enforcement is starting to completely change. Proactive police work has been eliminated in most departments. Everything now is based upon after the fact response. Even when that occurs, you will see very little action going forward Based upon policy from the powers that be are the prosecuting authority. I believe that Businesses and neighborhoods are going to have to pay extra for proactive law-enforcement. We pay off duty cops to patrol our neighborhood and act proactively when they see something suspicious. Business owners do the same in certain areas. You will see this across-the-board in less than 10 years, especially if the courts strike down immunity from civil suits.
