What is CSI?

Crime Scene Investigator is an employee of the Crime Scene Investigation who looks after complex scene investigations.

A CSI tends to collect crucial information at the crime scene and is responsible for the initial investigation of a scene. It then hands over all the collected information to the agency that probes the case. 

A crime scene investigator has the potential to transform a chaotic crime scene into hard evidence. An evident distinction of the CSI’s job is that the data collection takes place in the field rather than in a laboratory setting.

In addition, a CSI is responsible for collecting evidence as minor as a broken pin and preserving it carefully. In short, Crime Scene Investigators are trained forensic scientists on duty. 

To become a CSI, an applicant should have a bachelor’s degree in a related field, followed by on-the-job training, and earning CSI certifications and a State license.

Higher education may provide an applicant with advanced placement opportunities. An individual must be at least a 21-year-old US citizen and pass a vision, hearing, and physical test. 

Conclusively, a CSI must have critical thinking and problem-solving skills, the ability to remain focused and attention to detail.

Just like police ranks, a CSI can have promotions as an employee of the Crime Bureau Investigation. Thus, a CSI agent must possess determination, ready wit, and the ability to take up challenging investigations. 

What is FBI?

Abbreviated as FBI, the Federal Bureau Investigator is an employee of the Federal Bureau of Investigation who looks after the domestic security and intelligence service of the United States of America.

Federal Bureau Investigators handle investigations of large cases. These cases are federal and are not the task of local investigation agencies.

The job of an FBI agent is to gather evidence, interview witnesses, execute search warrants, and conduct surveillance. In addition, an FBI agent may also play a role in the prosecution of criminals by testifying in court.

While some agents work in the field, others look after cyber crimes or work in agency offices. The eligibility criterion to become an FBI agent has a few requirements. One should be a US citizen between 23 and 37 years of age.

A high moral character, clean record, at least 4 years of bachelorette degree, and 3 years of working experience are a prerequisite to be an eligible candidate.

Applicants also require a top-secret security clearance, a TS/SCI clearance, and a physical fitness test.

Becoming a Federal Bureau Investigator is not an easy task. In addition to the above requirements, an individual requires five years of service as a police officer, or as military personnel or as a prosecution lawyer.

An applicant also has to pass vision and hearing tests as a part of the process. Conclusively, the FBI has a demanding job with specific requirements.
