P.O.T.S question

In our world now, we have people who are becoming corrupt and also killing and stealing for their own needs. Like police becoming corrupt(as rare as it is), it still happens. With more corruption our police system is becoming more like in P.O.T.S. And with the increase of crime and less obligation to get those people, its become much harder for us to live. But also if we look around in our neighborhoods, towns, country, even the world you'll see that more and more people are becoming part of a walled in community believing that its "safer" then the outside world.
