I will coolly ask what is the matter. I need not be scared of police because I have never done anything wrong. The call may be for some good purpose also. Suddenly, one day two policemen came and knocked my house. I went and asked what they want. They said that they want to fix an automatic chip on the wall of my house, which will record the visit of beat police in the midnight. I took the chip and got it fixed. Even today, a police comes at 2.30 AM in the midnight, opens my gate, swipes on the chip and goes. It is a safety method. I have become a part of the police security. I am proud. We must not be scared at the word police. Police are there to protect the people. We must be positive.

Definetly not panic. I have worked in Security department of an organization and have seen Police personnel from close quarters. They are like us only and especially the newly recruited ones are quite educated and well mannered.
