What are the advantages and disadvantages of the FBI using a multiple hurdles approach to select special agents?

The FBI is one of the six bureaus of the U.S. Department of Justice and the primary criminal investigative agency of the federal government. The special agents who work for the FBI investigate people and organizations who violate federal statutes. These violations can be related to organized crime, white-collar crime, financial crime, civil rights violations, bank robberies, kidnapping, terrorism, foreign counterintelligence, and fugitive and drug trafficking matters. Special agents also work with other federal, state, and local law enforcement agencies. The work performed by special agents has a daily impact on the country’s security and the quality of life of all U.S. citizens.
