Law Enforcement 101

The primary role of law enforcement agencies is to serve and protect the public. Their mission is to enforce the law, prevent and detect crime and preserve peace within their jurisdictions. This requires a broad spectrum of duties including collecting criminal intelligence, conducting investigations, executing criminal warrants, subduing unruly or dangerous individuals and apprehending offenders.
Law enforcement must balance their obligation to protect individual freedoms with their responsibility to maintain a safe and orderly society. A large part of this responsibility must be accomplished by training and experience. The public holds law enforcement personnel to a high level of conduct, and expects officers to be calm and unflappable in all situations.
As the name implies, administration of the law is a key responsibility of law enforcement agencies. By ignoring or breaking laws, officers and other law enforcement officials undermine the public’s trust of the agencies which they serve. For this reason, it is important that law enforcement agencies place a high level of trust in their officers and employees.
Law enforcement agencies are composed of teams and divisions with various roles and responsibilities which work together to accomplish the agency’s mission. The functions of these divisions vary. For example , one division may focus on intelligence initiatives while another concentrates on crime prevention and patrol operations. Some divisions focus on criminal apprehension while others respond to emergency calls for assistance or focus on criminal investigations.
Administration of law enforcement agencies is a complex issue. In addition to enforcement, a law enforcement agency is charged with the difficult task of educating the public and maintaining the public’s trust. By taking part in community service events such as school programs, youth outreach programs, charity sports events, battles against drunk driving and other important issues, law enforcement agencies can increase their public profile and instill a greater sense of trust within the communities they serve.
Without the public’s trust and support, maintaining a safe and orderly society would be impossible. The relationship between law enforcement and the public is a complex one. However, these agencies understand the need for public cooperation, and work hard to achieve it.

History and Development of Criminal Justice

The foundation of modern law enforcement and criminal justice has been firmly rooted in centuries of development dating back to early societies. Over time, these systems have adapted and evolved to meet the needs and expectations of the society that utilizes them.
The earliest criminal codes, which date back to 418 B.C. in Ancient Greece, were the first attempts to outline laws and the punishments associated with infractions. In addition to punishment, ancient codes also focused on determining guilt, setting evidence standards, and identifying juries. However, it wasn’t until the Code of Hammurabi was established in 1772 B.C. that one of the first documented law enforcement systems emerged. Hammurabi’s criminal justice system focused on keeping the peace, as well as eliminating feuds and preventing private revenge against those accused of crimes.
In a move designed to standardize the laws, King Henry II instituted the royal court system in 1176 A.D. These courts included juries in their decentralized and localized decision-making process. In 1215 A.D., the Magna Carta set additional limits on the king’s power through a system of due process and procedural law. The Magna Carta also established a general set of laws, placing them above the king.
During the Middle Ages, the concept of policing appeared on the scene, as mobs and vigilante groups took the law into their own hands. By the 13th century, common law (law based on custom and case law) began to serve as a reference for settling disputes. Later, in the early 16th century, King Henry VIII formed the voluntary "thief takers" organization, responsible for capturing criminals who had evaded capture by the private citizens taking on policing duties.
Recognizing that on-the-ground experience was vital, Sir Robert Peel established the London Metropolitan Police Service in 1829, formalizing the creation of professional law enforcement. This "Peelian" reform established principles such as the need to seek cooperation and the importance of crime prevention versus detection. The Metropolitan Police also established the police uniform, which reflected that of the military.
Fast forward to the 20th century and the emergence of new ethical concerns. Issues such as forced confessions, coerced witness testimony and the admissibility of evidentiary material have undergone scrutiny. However, with the advent of technology and scientific advancements, such evidentiary challenges are being addressed.
Another developing line of questioning is that of police abuse and misconduct. The use of force, surveillance, unjustified police action leading to injury or death, false arrest and discrimination are all issues that continue to be areas of interest for sociologists and psychologists alike.
Yet with the creation of new criminal laws and with the development of modern day juries, we can see that the history and evolution of the criminal justice system, says recent advances in these areas, and the concerns of many, show that it continues to evolve in order to stay relevant and effective.

Key Elements of the Criminal Justice System

As the name suggests, the criminal justice system provides an avenue for governing criminal matters. It is no surprise to anyone that law enforcement agents are tasked with preventing and responding to crimes as they occur, but the criminal justice system is much more than police officers. A full criminal justice system includes three core components: law enforcement, the judiciary, and corrections.
Law enforcement officers strive to protect the public and enforce the law by preventing and responding to crime. They also identify and arrest those who have committed a crime. Law enforcement officers include not just our country’s police officers and sheriffs, but also game wardens, secret service agents, park rangers, and many more.
After an arrest, accused criminals generally hire a private defense attorney or are assigned one by the court to ensure they have an opportunity to have a fair trial. To determine innocence or guilt, judges make rulings on what evidence may be used in court and how the trial is to be conducted. Judges also preside over plea bargains and sentencing terms. The job of judges goes far beyond criminal matters, but this blog does not focus on any of their other responsibilities.
Corrections officers are responsible for the supervision of individuals and the management of facilities for those who are convicted of crimes. Corrections officers include jailers, parole and probation officers, and juvenile detention officers. Because of the high risk nature of this work, correctional facilities are highly secured and staff is highly trained.
The criminal justice system is comprised of law enforcement, the judiciary, and corrections components. Although they may each operate independently, they all play an important role in maintaining justice in our society.

The Role of Law Enforcement in Deterring Crime

Crime prevention encompasses a range of proactive measures designed to prevent crime or reduce the risk of crime occurring. Law enforcement is just one part of a multi-faceted approach to crime prevention ideally involving the collaboration of communities, schools, health service providers, businesses, and residents in addition to law enforcement agencies. Where opportunities for crime to occur are reduced and awareness is raised in the community about how to deter crime, crime is adaptive and will shift to a different area. At the same time, while crime prevention efforts are best achieved by collaboration, law enforcement agencies ultimately have the responsibility to hold criminals accountable for their actions.
Community policing is the approach law enforcement agencies take to create collaborative partnerships with people in the communities they serve. The goal is to develop a common vision and strategy for the extent and level of services and resources dedicated to specific criminal problems in neighborhoods. Community policing emphasizes prevention and problem solving in a proactive response to crime. The role of law enforcement in community policing includes the traditional patrol duties, but officers also address issues that contribute to crime and focus additional resources on problem-solving strategies and performance measurements in concert with residents.
The criminal justice system has embraced technology in crime prevention efforts. On the front lines, crime mapping software helps law enforcement identify crime trends that require attention. Officers have mobile data computer technology to access data in real time and use computerized databases to track leads and discover clues. Global positioning system technology is used to track delivery trucks and mobile high-definition video recorders monitor traffic. In addition to the street cameras police departments use, other agencies can use the video captured by smart-cities traffic and security cameras. With the prevalence of so much data, predictive software now helps law enforcement sift through available data to flag potential crimes for prevention action, even by remote drones.

Laws Regulating Law Enforcement

A multitude of legal principles and constitutional guarantees exist to govern how our police and investigative stakeholders enforce the laws and investigate suspected criminal conduct. In the coming sections, we will break down this framework by providing information on due process; search and seizure; and a few other concepts that you should know.
This is a simple enough concept, although it has been known to break down now and again. It says that law enforcement officers may not deprive you of your rights without due process. This means that you should have (and usually do have) advance warning of what you may or may not be charged with and that you will have the opportunity to present evidence in your favor before the court in a fair set of proceedings. In most cases, this notification comes in the form of an arrest, a ticket, a promise to appear, or a summons to appear. Duty and procedure aside, this is a statement of one of the fundamental concepts of the modern American judicial system and the American way of life: that you are granted a full and fair hearing with a neutral party before being deprived of your liberty and that you are entitled in most cases to some consideration of mitigating factors.
The Fourth Amendment to the United States Constitution is the touchstone for questions of search and seizure and is based in the protections against "unreasonable searches and seizures." The basic idea is that a broad and unlimited power to search and seize would erode the protections of the right to security of person. This amendment also provides that no warrant shall be issued, except for upon probable cause supported by Oath or affirmation, and it describes the requirement of the warrant as being "particularly" describing the place to be searched and the persons or things to be seized.
Once again, this is a simple enough concept that knows failure from time to time. In order for police and other investigative stakeholders to search and seize within your home or vehicle, there must be a warrant. Similarly, searches of your phone, tablet , or computer must have a warrant attached. There is also often a requirement that potentially damaging material, such as private photographs, be concealed from the eyes of those who do not range within the scope of the investigation. In order to be adequate, the warrant must be specific in its nature and not simply a general order to search and seize all of a particular person’s belongings. In addition, the warrant must be based on probable cause, so the officer or investigator cannot rely on his or her own biases or prejudices in what to search for and where to search. Most importantly, a search and seizure that is considered reasonable is permissible, even if it violates these protections. What can be more troublesome is a warrant that is facially invalid, promulgated without a judge’s signature, or unsupported by the evidence. Such things might technically be reasonable, but they do violate your due process rights, provided you have standing to challenge them.
This tricky term refers to the rights possessed by all individuals when interacting with law enforcement officers and investigative stakeholders. The basic idea is that, once being detained (i.e., arrested, cited, ticketed, etc.), all your rights become suspended. Nothing could be further from the truth.
Rather, you retain all of your rights throughout the course of an interaction with law enforcement, although you may retain no right to be free from arrest and detention, if there is probable cause of a crime having been committed. This means that, on the whole, you were only supposed to be arrested for a crime you actually committed and no less (although many people are arrested on the insufficient or incorrect basis of alleged probable cause). In addition, you have the right to remain silent (and to engage in an attorney/client privilege with the prosecutor) and you have the right to be free from unreasonable search and seizure that would deny you your privacy and security. This generally means that there is a separating line between reasonable detainment and unlawful home invasion, although there are some gray areas.

How to Start a Career in Law Enforcement and Criminal Justice

The most obvious and probably the most sought-after career opportunities in criminal justice are those available within the law enforcement community. However, there are also numerous professional opportunities available at the state and federal levels as well. The majority of these positions are with local or state law enforcement agencies. Common positions include police officers, sheriff’s deputies, criminal investigators and detectives, police intelligence specialists and many other specialist and support roles. Police exam preparation services are available throughout the country offering pre-licensing training and education services.
While there is no formal standard for police licensing requirements, the majority of law enforcement agencies do require the following: The next largest segment of law enforcement jobs are those available at the federal level. The FBI, DEA, US Secret Service, Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), Immigration & Custom Enforcement (ICE), US Marshalls, Border Patrol, US Army CID, Air Force Office of Special Investigations, NCIS, CIA, and the Department of Homeland Security all hire criminal justice graduates trained at the Bachelor’s degree level. The FBI and DEA positions require Master’s degree graduates or higher.
There are a number of other career opportunities in federal criminal justice besides those in law enforcement. The Department of Justice, the Federal Bureau of Prisons, the and Department of Taxation hire Criminal Justice graduates at the Assistant, Specialist and Clerk levels. Most federal agencies require college graduates. Senior level positions (Administrative Officers, examiners, investigators) usually require a Master’s degree or higher.
There are a variety of career options available with state and municipal government, too. Aside from police agencies, state employment includes the Department of Corrections. State and county correctional facilities, halfway houses and community release centers all hire correctional treatment specialists, parole officers and related positions.
Accountants and Auditors, Fire Inspectors, Forensic Scientists, Court Clerks, Victim Assistance Counsels, Court Services and Probation Officers, Immigration and Customs Specialists, mental health counselors and many others also hire Criminal Justice College graduates.

Current Issues in Law Enforcement

Law enforcement agencies today grapple with an array of unprecedented challenges that have transformed the landscape of crime and public safety. The advent of new technologies has given rise to cybercrime, which crosses traditional borders and poses unique investigative hurdles. Police are now required to have specialized training in digital forensics and cybersecurity to address threats that previously existed only in the physical realm. This added layer of complexity requires law enforcement agencies to keep pace with the rapidly evolving digital landscape, often without the necessary resources or legal frameworks in place.
Moreover, the relationship between law enforcement and the communities they serve has become strained in many areas. High-profile instances of police misconduct or abuse of power have led to a loss of trust and confidence in law enforcement among vulnerable communities, which in turn has hampered efforts to gather intelligence and facilitate investigations. Increased scrutiny of police methods, including the use of body cameras and social media, can be both a blessing and a curse. Transparency helps build trust, but can also foster hostility towards officers who feel exposed on social media or micromanaged by activists and the public.
Technological advances have also impacted policing methods. Surveillance technologies like drones and facial recognition software can provide critical support to law enforcement, but lead to questions of civil liberties and over-policing. Advances in forensic science continue to provide new avenues for identifying and catching criminals, but may also result in wrongful convictions if practitioners do not adhere to strict best practices. In a world of competing and conflicting priorities, it is critical that police departments and policymakers carefully consider the potential risks and drawbacks of any new technology.
In addition to these issues, law enforcement agencies are confronted with budgetary constraints that limit their ability to respond effectively to modern challenges. Decreased budgets are a byproduct of weakened public perceptions and diminished funding. As a result, agencies must make tough decisions about hiring, training and investment in new techniques and technologies. In order to respond to today’s threats to public safety, law enforcement agencies are required to proactively engage the public, recruit a diverse array of qualified applicants from the communities they serve, and develop new strategies that foster healthy relationships with the people they protect.

Future Directions in Law Enforcement and Criminal Justice

Looking ahead, both law enforcement and the criminal justice system are likely to continue evolving to meet changing societal needs. Several future trends can be anticipated based on current developments and public discourse. Emerging Technologies: As technology continues to advance at a rapid pace, we can expect to see further integration of technological tools within law enforcement practices. This may include the use of artificial intelligence in predictive policing, more sophisticated body-worn cameras, and improved data-sharing platforms that facilitate close collaboration among law enforcement agencies. In addition, technologies such as facial recognition software and license plate readers are likely to become even more prevalent despite ongoing debates about civil liberties infringement. Policy Shifts: Ongoing discussions and movements calling for criminal justice reform will continue to shape policies at local, state, and national levels. Changes to drug policies and decriminalization efforts around the country may reshape the role of enforcement within law enforcement agencies by shifting their focus towards more serious offenses . Moreover, reforms regarding policing practices aimed at reducing officer-civilian interactions could lead to a fundamental rethinking of the police function within communities. Evolving Public Expectations: As public awareness regarding criminal justice issues increases, the demand for transparency and accountability measures from law enforcement agencies will likely become more pronounced. Public outcry over excessive use of force incidents has led many departments to adopt body-worn cameras and other transparency measures in order to increase accountability. Going forward, we can expect a continued push towards community-based policing initiatives and more preemptive measures aimed at preventing crime as communities seek more holistic solutions to social problems. Overall, the future of law enforcement and the criminal justice system will continue to transform as both of these sectors strive to meet the needs of society. Coping with the implications of emerging technologies, adapting to policy changes, and responding to evolving public expectations will all play critical roles in determining the trajectory of law enforcement and the criminal justice system in the years to come.
