The world devoid of such things as art, science, music, literature, painting, sculpture, etc. is only a primitive world of the savages. This is how the absence of the police of which the policeman is a representative can turn back the clock of civilization.
As an individual, the policeman is not considered of much importance except by the ignorant illiterate poor people. The policeman has to do onerous duties to maintain law and order. He gets only a small salary for this.
Some policemen indulge in undesirable activities such as accepting bribes, joining hands with criminals, etc. We must, however, remember that all policemen are not bad. We must assist the policemen in nabbing criminals and in doing other duties.
