When Do Forensic Investigators Need to Carry Guns and Interview Witnesses/Suspects?

Forensic investigators typically do not carry guns unless they are part of a law enforcement agency such as the police or a specialized forensic unit that has sworn officers. Their primary role is to collect, preserve, and analyze physical evidence from crime scenes, not to engage in law enforcement activities like arrests or confrontations.

Carrying Guns

For most forensic investigators, the absence of a firearm is a defining characteristic of their role. However, there are exceptions. Some investigators may belong to sworn police departments where carrying a gun is part of their duty. In other cases, such as specialized forensic units, they might carry firearms to protect themselves during high-risk situations or to handle sensitive evidence.

Crime scene investigations vary in their approach to safety and security. In some jurisdictions, forensic investigators might carry a gun at crime scenes, particularly if the environment is deemed dangerous or if the crime itself involves a high risk of violence. However, as safety and security practices evolve, this practice is becoming less common.

Interviewing Witnesses and Suspects

Forensic investigators may participate in the interviewing of witnesses and suspects, but these activities often depend on the context. Their role is to gather information that can support or refute the evidence they have collected. They may provide valuable insights into the evidence to suspects or assist detectives in formulating questions based on their findings. However, the actual interrogation of witnesses and suspects is typically conducted by trained law enforcement officers such as detectives.

Responsibility for Interviews

In most cases, the responsibility for interviewing witnesses and suspects lies with trained law enforcement personnel. These officers have received specialized training in interrogation techniques and communications, which is crucial for obtaining reliable and accurate information. Forensic investigators, on the other hand, are primarily focused on the collection, preservation, and analysis of physical evidence.

Real-World Examples

I have over 15 years of experience as a crime scene investigator in two different police departments. In one department, as a sworn officer, I was required to wear a gun in a shoulder holster. In the other department, as a civilian, I did not carry a gun. My experience across these departments highlights the variability in the roles and responsibilities of forensic investigators.

In one state, I was trained to carry a gun and we did so at crime scenes. However, this practice is becoming less common as new safety protocols and tactics are developed. It's important to note that forensic analysts do not typically interview witnesses or suspects. Their expertise lies in analyzing evidence, which is crucial for building a solid case in court.

Conclusion

In summary, the role of forensic investigators is primarily focused on the collection, preservation, and analysis of physical evidence. While they may carry firearms in certain circumstances, their primary responsibility is not law enforcement but rather the scientific examination of evidence. Interviews of witnesses and suspects are typically conducted by trained law enforcement officers, who have the necessary skills and experience for this task.
