The police departments have come a long way from the way they were many years ago. The police have changed for the better but there is still room for improvement. In policing today there are a lot more officers, detectives, and other law enforcement officials accounted for then there was in the past years. When we have all of these people in the criminal system, it has made the government to be able to provide better protection for the people in the communities. Policing in the past and in the present there are many different outlooks of how the policing functions.. These functions stem from different levels of law enforcement which includes the local, state, and federal organizational levels. These are very important parts of the criminal justice system, because every individual within these levels must be sure to protect citizens, enforce law, and perform the duties that are required of them in order to keep the United States safe from criminals and terrorist attacks from other foreign countries that might try to attack the United States. As years have passed on within policing, there are many possible future changes that will have an effect in the field of policing.
Within each level of policing there are many different roles in which every individual in the policing field must take part in if they are going to be on the law enforcement team. I say this because this is a very serious 24/7 operation and the duties are never ending for each of the levels. The local law enforcement agencies were put in place to do routine patrol within the communities that are within their jurisdiction. Local police officers are also able to assist with emergency services, upholding traffic enforcement, and conduct criminal investigations. These local police officers overall role is to ensure that all citizens are safe within their communities. To ensure residents in their community, officers will ensure that they are safe by communication.
