Section 33(a) in Police Regulations, Bengal , 1943
(a)No police force can work successfully unless it wins the respect and goodwill of the public and secures its co-operation. All ranks, therefore, while being firm in the execution of their duty, must show forbearance, civility and courtesy towards all classes. Officers of superior rank must not only observe this instruction themselves but on all occasions impress their subordinates with the necessity of causing as little friction as possible in the performance of their duties.
