 These students in this module, we are going to discuss the role of police in criminal justice system. So, police are basically responsible for enforcing laws and maintaining order in the society. Without police, it would be impossible to have law and order in any society, particularly when we talk about the modern societies. So, the police are primary law enforcement agency in most of the countries, including Pakistan. First of all, the organization or the agency that comes into action is a police in any crime and the police work as a central pillar to maintain law and order in this system. The role of police includes investigating the crimes, making arrests and protecting public safety. So, not only the work of the police is to apprehend the crime, but investigate it, detect it and find out who the real culprit is. The role of the police in this criminal justice system, particularly the investigating role, is very important. And then, protecting the public safety is also very important. In the form of a potential threat, the police are deployed. And first of all, it is seen that in such a situation, in which the potential threat can be a public threat, the police play their role and apprehend the crime. So, the police have the significant power and authority, including the ability to use force and deprive individuals of their liberty. The criminals or potential criminals apprehend the police and also stop the crime. But there is a criticism on this as well. For example, in the global world, we see that the police also use their authority and apprehend such individuals. Or they implicate the justice system in such a way that the innocent people are also forced into this system because of the police. So, the role of the police is very important. Not only in the investigation, but in the apprehension of the potential culprits. In fact, in establishing transparency, the role is very important. So that the justice system, by trusting and relying on the police investigation, can establish such a justice that is acceptable for the people. So, the police are subject to scrutiny and oversight to ensure that they act within the law and respect the rights of the citizens. When we talk about the rights of the citizens, obviously the human rights are very important. Freedom or liberty, individual freedom, freedom of expression. All these rights are kept in mind. Especially, the police have to see that if someone has committed a crime, then despite this, the rights of the individual should be respected and treated according to their rights. So, in Pakistan, the police are organized at both the federal and provincial levels and there are a range of specialized police units for different types of crimes. So, on a regional level, our police agencies are present, federal level culprits are present, provincial level culprits are present. So, these all agencies are contributing for the restoration of peace in society.
