Which of the following is not a role of the FBI in fighting computer crime?

• A. Capture criminals behind serious computer intrusions and the spread of malicious code
• B. Stop online sexual predators who produce or share child pornography
• C. Prosecute crimes related to encryption, e-commerce, and intellectual property crimes
• D. Dismantle national and transnational organized crime groups engaging in Internet fraud

Answer: (C)

The main idea here is the distinction between investigation and prosecution. The FBI's core function in fighting computer crime is to investigate cyber offenses, gather evidence, disrupt operations, and make arrests, so that cases can be brought to court. They work on cases involving serious computer intrusions, malware, online exploitation, and large-scale internet fraud, often coordinating with other agencies and task forces.

What makes the third statement the best choice is that prosecutions are carried out by the Department of Justice, specifically the U.S. Attorneys' Offices, not by the FBI. The FBI can pursue and build a case, but the actual charging, court proceedings, and seeking convictions are the prosecutor’s role. So saying the FBI prosecutes encryption, e-commerce, and intellectual property crimes misstates the division of responsibilities.

The other options align with typical investigative actions the FBI performs: pursuing those behind significant intrusions and destructive malware; combating online child exploitation; and working to dismantle organized crime networks engaged in internet fraud.
