In this episode, we talk about history repeating itself. Lessons never learned from past experience. How? Reducing security because of the absence of attacks is tempting, but dangerous! It removes the deterrent that deflected attacks to softer targets elsewhere. People want to live and work where they feel safe.  The visible presence of security is a necessary element in creating and sustaining the perception of a safe environment.  Even a small amount of crime coupled with visible reduction of security presence erodes the perception of safety. So what do most people do when nothing happens? They cut security!
