Critical thinking in criminal justice: Analyzing scenarios and making decisions
As a criminal justice professional, it’s likely that you will have to deal with complex situations that require making difficult decisions. Often, these decisions can have a lasting impact on the lives of others. In these circumstances, critical thinking skills can help you normalize crisis situations, resolve disputes, apprehend suspects and work to uphold justice as you fulfill your duties.
Critical thinking is a cognitive skill that can be applied to many occupations and aspects of daily life.
Critical thinking is a cognitive skill that can be applied to many occupations and aspects of daily life. Generally, critical thinking involves the cognitive process of analyzing, evaluating and interpreting information rationally and objectively. When applied to scenarios in criminal justice, critical thinking helps you explore multiple perspectives and challenge assumptions to reach a well-informed conclusion. Ideally, critical thinking leads to creative problem-solving and better decision-making.
“Critical thinking is very important for all criminal justice professionals. In general, critical thinking encourages improved decision-making processes. Long gone are the days of simply gathering the facts at a crime scene and prosecuting the crime. By critically examining problems, we can work towards more ethical decisions that address habitual community problems. As we reduce the number of occurrences that need law enforcement interactions, we will see many secondary benefits, including reduction in incarceration costs, use of force and reduction of victimization,” said James Ebert, MJA, Professor in Criminal Justice, Purdue University Global.
Steps involved in using critical thinking in criminal justice
In emergency situations, critical thinking facilitates prompt, well-informed decisions. This can be valuable in high-pressure and potentially volatile circumstances where fast judgment is needed to protect lives and avoid disasters. When used during emergencies, critical thinking helps criminal justice professionals follow established protocols and policies. It also helps you apply the fundamentals of ethics, reasoning and logic in the given situation.
In non-emergency situations, critical thinking can help criminal justice professionals evaluate the reliability and validity of evidence, recognize patterns and develop creative solutions. It can contribute to ethical decision-making, effective communication and thoughtful policy analysis as criminal justice professionals work together and across departments.
Ebert describes the following “outside-in approach” when applying critical thinking to criminal justice situations:
Step 1: Determine whether a crime was committed.
What does the law say about my investigation? Are the elements of crime present? Do we have legal jurisdiction for the potential crime? If these questions are answered in the affirmative, we can begin evaluating evidence of the crime.
Step 2: Evaluate the evidence of the crime.
Conducting an investigation not only documents the events of the crime but also elicits the truth of the scene regardless of whether that truth helps or hurts the prosecution or defense cases.
Step 3: Weigh findings against policies.
After the investigation, critical thinking involves weighing the previous information against the formal and informal policies of the departments involved.
Step 4: Apply social intelligence.
The last step is for the responding officers to ensure that social intelligence (the ability to understand the feelings, thoughts and behaviors of others and yourself) is used throughout the process.
Applying critical thinking to criminal justice requires that you approach the situation with an open mind. Social intelligence can help you put aside biases and preconceptions so you can more accurately listen and observe. This makes it easier to identify the information you need to resolve a situation or reach a well-considered conclusion.
Common scenarios involving critical thinking
Critical thinking is crucial in criminal justice scenarios that involve making different types of decisions, gathering evidence and evaluating information. These scenarios can occur in relation to investigations, interviews, evidence evaluation and legal procedures. The following examples describe ways in which critical thinking skills are used in the field of criminal justice:
Making decisions at an active crime scene or crisis intervention
Criminal justice professionals involved in an active crime scene or crisis intervention must be prepared to apply critical thinking skills to make split-second decisions on the spot. This means you’ll have little time to determine legal jurisdiction, evaluate evidence and weigh your findings against formal and informal policies.
“For this scenario, time may not be on your side. So, critical thinking may not be as in-depth as we would like. Still, ensure a crime was committed, the judication is correct, the evidence of the crime is evaluated and the situation is addressed according to applicable laws/policies,” said Ebert.
The process continues after the order is restored. “After the active scene is resolved, it is essential to debrief other law enforcement officials to allow a greater opportunity to think critically about that event and address possible changes you would like to see if a similar event were to occur,” said Ebert.
Evaluating evidence/investigating a crime scene
Investigating a crime scene involves evaluating evidence, identifying potential witnesses, determining their credibility and weighing the relevance of their statements. These findings can affect the decision to identify a suspect, the type of charges brought and the way a case is prosecuted. Critical thinking skills help ensure that the investigation supports the circumstances of the crime.
“Critically thinking about investigating a crime scene starts with why and how we got here to the crime scene. Most likely, you were dispatched to the scene to start gathering information from the dispatch center. Often, the information will be limited and unreliable,” said Ebert.
To apply critical thinking skills in these scenarios, Eber advises, “Arrive at the scene and ensure all parties’ safety the best you can. Consider what laws have been committed and ensure the scene is processed according to your agency’s policies and state law. Remember, ethically, you are bound to document and collect information that does not support your case but also may support a suspect’s defense.”
Interviewing a witness or suspect
When it’s necessary to learn more about a possible crime or incident, criminal justice professionals speak with witnesses. In this situation, critical thinking skills can help you assess a witness’s reliability and identify any contradictions in their statements. Critical thinking skills also guide you in staying within established policies to avoid tarnishing the value of a witness statement or suspect confession.
“Critical thinking while conducting interviews starts with ethical decision-making. The desire to get the confession should never overshadow the legal protections provided by the U.S. Constitution and other state laws,” said Ebert.
Certain strategies can facilitate critical thinking and improve the accuracy and effectiveness of interviews. “If the personnel are available, have a second person sit in with you during interviews or watch from another room. The second person can give you a bigger picture of what was said and not said during the interview. Critical thinking during interviews always helps us to work through why suspects/witnesses say what they say,” said Ebert.
Ways to develop critical thinking skills
The curriculum for a criminal justice degree typically involves analyzing case studies, discussing ethical quandaries and participating in simulations. This will help you apply theoretical models and professional protocols to real-world situations. As you grow and advance in your criminal justice career, this foundation will help you become more comfortable with the critical thinking process so that it becomes second nature.
Beyond your education, you can work to develop critical thinking skills by staying informed about new technologies, laws and societal changes that can impact all aspects of criminal justice. To build on your theoretical knowledge, commit to lifelong learning.
Ebert suggests the following strategies to develop and improve your critical thinking skills in criminal justice:
“I would advise all newcomers to criminal justice to stay ethically sound. Understand that the system rarely changes as fast as you want. Critically thinking about events that impact the criminal justice system will allow more job satisfaction by finding better long-term ethical answers to problems,” said Ebert. “Finally, I would tell all new professionals in the field of criminal justice to learn how to use social intelligence. Social intelligence makes the process of conducting critical thinking much easier.”
