What is the role of the DEA?

The role of the Drug Enforcement Administration (DEA) primarily focuses on combating drug trafficking and distribution within the United States. This includes enforcing the controlled substances laws and regulations, targeting illegal drug operations, and ensuring that individuals and organizations comply with the legal frameworks surrounding drug-related activities. The DEA works to dismantle drug trafficking organizations by gathering intelligence, conducting investigations, and collaborating with other law enforcement agencies to address the complex issues of drug abuse and trafficking.

While the other options touch on various aspects of law enforcement, they do not align with the core responsibilities of the DEA. Protecting federal witnesses, conducting background checks, and investigating financial crimes are duties typically associated with different federal agencies such as the U.S. Marshals Service, the FBI, or the Treasury Department. Therefore, the correct answer accurately reflects the DEA’s mandate to focus specifically on drug-related crime and the enforcement of drug laws.
