Just want to illustrate couple of incidents on physical security that we commonly observe.
Once while driving through a technology park, I was stopped by a couple of security personnel and they requested me to open the boot of my car and there was the second one running a mirror underneath my car and looking at something. Since the amount of different car models that I has come out in market, I assumed that the bottom of every car must be different and out of curiosity, I just enquired with the security personnel, as to what is he looking for and you will be amazed with the answer. “I am not sure sir, they have asked me to check and I am checking”.
