Q... What do you understand by the preventive action of the police ?
PREVENTIVE ACTION OF POLICE
========================
========================

A police officer must interfere effectively for the prevention of an offence. He cannot shirk his duty of interposing effectively by being content with passing an oral order not to do a certain act.

The intervention is justified only when there is a probability of the commission of an offence . A police officer is not justified in removing an axe carried by a person under the impression that such person was carried it on his way to attack his enemy.

Preventive actions of the police are following:


TO PREVENT COGNIZABLE OFFENCES
============================
============================

According to section 149 of criminal procedure code " every police officer may interpose for the purpose of preventing and shall, to the best of his ability prevent the commission of any cognizable offence".


INFORMATION OF DESIGN TO COMMIT SUCH OFFENCES
========================================
========================================

According to section 150 of criminal procedure code, " every police officer recieving information of a design to commit any cognizable offence, shall communicate such information to the police officer to whom he is sub-ordinate, and to any such officer whose duty is to prevent or take cognizance of the commission of any such offence".


ARREST TO PREVENT SUCH OFFENCES
==================================
==================================

According to section 151 of criminal procedure code, " a police officer knowing of a design to commit any cognizable offence may arrest, without the orders from a magistrate and without a warrant, the person so designing, if it appears to such officer that the commission of the offence cannot be otherwise prevented".


PREVENTION OF INJURY TO PUBLIC PROPERTY:
====================================
====================================

According to section 152 of criminal procedure code, " a police officer may of his own authority interpose to prevent any injury attempted to be committed in his view to any public property, movable or immovable, or the removal or injury of any public landmark or buoy or other mark used for navigation".


INSPECTION OF WEIGHTS AND MEASURES:
====================================
====================================

According to section 153 of criminal procedure code,

1. any officer incharge of a police station may, without a warrant, enter any place within the limits of such station for the purpose of inspecting or searching for any weights or measures or instruments for weighing, used or kept therein, whenever he has reason to believe that there are in such place any weights, measures or instruments for weighing which are false".

2. If he finds in such place any weights, measures or instruments for weighing which are false, he may seize the same, and shall forthwith give information of such seizure to a magistrate having jurisdiction.
