Final answer:
The FBI's role varies depending on the case, and whether their behavior is proper or not can be a subjective matter.
Step-by-step explanation:
The FBI played a role in various cases throughout history, but it is important to specify which case you are referring to. In general, the FBI's role is to investigate federal crimes, gather intelligence, and protect U.S. national security. However, proper behavior for the FBI is subjective and can vary based on individual opinions and the context of each case.
For example, in the case of the warrantless domestic wiretapping program implemented by the National Security Agency (NSA) in 2002, some people may argue that the FBI's involvement in this program was not proper behavior because it violated the Fourth Amendment's protection against unreasonable searches and seizures. On the other hand, others may argue that the FBI's role in gathering intelligence to prevent potential terrorist attacks justified their involvement.
In another historical example, the FBI's counterintelligence program, COINTELPRO, targeted various groups including civil rights activists, feminists, and anti-war protestors. Many people criticized the FBI for overstepping its authority and infringing on individuals' rights.
