Introduction to law enforcement

Considering a career in law enforcement means a commitment to the greater good. Police officers and those in similar roles pledge to use their authority to serve others, following the line of the law while treating others with respect. Successful law enforcement officers exhibit self-control, impartiality, and an intersectional approach as they work with people from varying backgrounds. Coupled with natural skills in communication and proper training, these qualities are critical for the modern law enforcement officer.

From a practical perspective, incoming officers can look forward to healthy growth in the industry at large. Over the next 8 years, the law enforcement workforce is projected to increase by 5%, a faster pace than the national average. This indicates a clear need for additional workers interested in protecting their communities, states, and country.

Law enforcement today

Law enforcement is under increasing scrutiny. As a result of several high-profile cases, there have been increased public calls for police reform. There are several emerging trends developing within the field to respond to this new landscape. New officers need to be willing to adopt these fresh approaches.

Community-oriented policing has taken the spotlight as a response to increasing tensions between the police and public. This strategy involves focusing on a collaborative approach to the relationship between local communities and their police departments. Research shows that the best way to use community policing successfully is to assure officers are trained at the college level. When new recruits have this educational background, they have been shown to use deadly force less often, exhibit tolerance, and demonstrate a deeper understanding of the criminal justice system.

Law enforcement professionals are also increasing their use of technology and tools. This includes leveraging social media, body cameras, facial recognition, drones, and even robots. Using these sophisticated tools, police officers free up time to focus on building strong relationships with the community. These tools also improve transparency, which builds public trust and cooperation.

To further evolve with the times, there is an effort in many police departments to increase workforce diversity by gender. Compared to 3% of total officers in 1970, women now make up 12.6%. Women in the force are lauded for their skills in resolving conflicts and community organizing, making this change a key piece of the puzzle when looking into the future of policing.

Complementing this trend, leadership positions are increasingly filled by younger generations. As the skills to lead in this field increase in complexity, younger officers are opting to get their master’s degree to build the competences they need to lead effectively. It follows that, in contrast to their predecessors, this generation has a more inclusive and tolerant approach to leadership.

Finally, the threat of cyber crime cannot be overlooked when considering the modern evolution of policing. This threat is growing exponentially, with losses exceeding $4 billion in 2020. As an incoming recruit, tailoring your studies with a degree in cybersecurity could put you on the front lines of this latest frontier of policing.

Getting involved in law enforcement today is an increasingly complex endeavor. Alongside these ongoing changes, however, the traditional law enforcement functions and activities continue.

Levels of law enforcement

When entering into a job in law enforcement, there are 3 possible levels of government where you can find employment. New recruits need to consider the benefits and downsides of each, including whether they would like to work in a traditional or more nuanced capacity.


Local law enforcement includes police departments within municipal, county, tribal, and regional areas that are given authority by the area’s governing body. They are responsible for upholding the laws within their jurisdiction by patrolling their communities and investigating local crime. Local law enforcement agencies include city police departments, county sheriffs’ offices, district attorneys’ offices, and transit authority police.


State law enforcement agencies are responsible for highway patrol, state-wide investigations, and assisting local police. Agencies include state police, campus police, coast guard, military police, and park police.


Federal agencies are responsible for upholding federal laws, which apply throughout the entire United States. Responsibilities include criminal investigation and enforcement, inspections, court operations, and corrections. Those employed at the federal level may work for agencies such as the Federal Bureau of Investigation (FBI), the Drug Enforcement Agency (DEA), the Bureau of Alcohol, Tobacco, and Firearms (ATF), or the Federal Bureau of Prisons.

Careers in law enforcement

Police departments have a ranking system that mimics the military. Though possibly the most well-known, the classic position of police officer is considered an entry-level role, and many officers have the ambition to climb the ranks to more advanced positions. While titles vary by department, most follow a system similar to the following:

  • Police officer
  • Detective
  • Sergeant
  • Lieutenant
  • Captain
  • Major
  • Colonel
  • Commander
  • Deputy chief of police
  • Chief of police

Unsurprisingly, moving up the ranks means taking on more responsibility and supervision of others in the department. Those at the highest levels work directly with politicians and lawmakers, setting policies that affect entire cities and regions. Listed below are descriptions of some of the most common positions.

Sergeants supervise police officers, getting briefs on incidents from previous shifts and deducing trends in crime. They monitor the police radio to make sure officers’ shifts are running according to regulations and review officers’ reports.

Similar to detectives, sergeants do a lot of administrative work, though they are required to work night shifts as police officers do. In addition to standard policing activities, sergeants are also involved in community outreach efforts such as teaching at local schools. They may also train police officers in areas like handling DUI (driving under the influence) incidents.

    Crime scene investigators, or CSIs, are known by many names. These include titles like evidence technician, forensic investigator, crime scene analyst, or forensic science technician. While specific duties are defined by individual departments and thus vary, these investigators typically collect and analyze evidence from crime scenes. Their job is to support the detective in charge of the case by performing the following tasks:

    • keeping records and reports on findings, methodology, and techniques
    • collecting and storing evidence
    • testifying in court about methodology and techniques used in a given case
    • using equipment to document evidence or crime scenes
    • examining crime scenes
    • contacting sources to get evidence for investigations

    Who is best suited to be a crime scene investigator?

    There are several skills and abilities that make someone a great CSI. A detail-oriented approach to all aspects of their job allow CSIs to assure the information they catalog and report is highly accurate and easy to understand. This quality extends to their communication skills as well. The best CSIs give their full attention to those they are interviewing, asking open questions that allow them to gather the most valuable information they can.

    As CSIs spend a lot of time documenting and recording evidence, it is important that they write in clear, complete prose so that others working on a given case can easily understand their findings. They need a high degree of accuracy when transcribing accounts or entering data.

    There is a great deal of specialized knowledge required in this role. A strong background in chemistry is key to success, as CSIs analyze compounds to be used as evidence in criminal investigations. CSIs use a variety of tools, such as evidence collection kits, footprint lifters, lasers, specimen collection containers, and ultraviolent UV lamps.

    Successful CSIs enjoy a varied working environment that includes both administrative and field activities. This job offers some freedom to make decisions and work independently, though it is still necessary to follow specific protocols where required. Most CSI roles involve working indoors in a laboratory, so those in this position tend to thrive in this predictable, controlled environment.

    Education requirements

    While some CSIs start as police officers, many civilians also enter into the role. Degree requirements depend on individual departments. Smaller or rural agencies often do not require a degree compared to larger ones. If you decide to get a degree, finding a program that helps you learn the specific skills involved in crime scene investigation will assure you are prepared for the role. A bachelor’s degree in criminal justice or forensic science are some of the most common degrees earned by CSIs.
