Security is in one’s eyes. Whether this perception is it be found in the one who is supposed to be watching while she/he gets an important text message or the one looking to find that hole which is not fully; covered security can be seen and felt. For as long as those who would attempt to evade it believe their chances are less then their success rate and 
the punishment hurts more then the crime they will not attempt to evade the fence. Yet if perception changes by those who cross then security is not worth the money it’s printed on. Security and reality therefore is a perception/power game where one will attempt to prove the other is weaker.
