  The criminal justice system is a wide and varied field. Corrections, law enforcement and the court system are components of this system. Law enforcement pertains to issues surrounding police, whether it's police procedures or behavior. If you are writing a research paper on law enforcement, there are myriad topics to choose from. As this is such a broad topic, you can take any one of the topics and write it from a unique angle.
  
  

Police Corruption

• One topic to choose for a law enforcement research paper is police corruption. This refers to police officers abusing their own authority for some type of personal gain. Some typical forms of corruption include extortion, selling drugs, bribery or selling stolen property. Another aspect of police corruption that you can focus on is departmental corruption. This occurs when there is a pattern of this type of misconduct within a unit that may be tolerated by supervisors.
  
  

Stress

• Law enforcement officers are under a lot of stress. This can lead to burn out or even suicide. Focus on police suicide or rates of post traumatic stress disorder as relevant research paper topics. Consider writing your paper about ways in which police departments can reduce the stress that police officers experience. There are particular policies that can be helpful. Discuss those policies in your research paper.
  
  

Evidence Collection

• One of the main duties of police officers and detectives is to process the crime scene, including preserving and packaging evidence. To do so, they must follow specific procedures and use specialized tools. It is incredibly easy to contaminate a crime scene and destroy evidence, so improper management and processing of a crime scene can cause a case to go unsolved. Write a research paper that lists and explains the processes for identifying, preserving and packaging evidence at crime scenes.
