Clearly if the police could get away ignoring the fact that you came in and took the land, they would. I would make a strong delineation between the adjudication of property rights and the enforcement of property rights. Those are two different things, and it has ever been the case that individuals frequently must act in an enforcement capacity. Potentially, if you tried to take someone's land, they will shoot you. That is enforcement. Adjudication happens when a judge says they were in the right.
