The FBI was once an organization of integrity.
Perhaps in J. Edgar Hoover's time, but he has been gone for over 40 years. One thing a Trump Administration must do is to thoroughly revamp Federal law enforcement, shutting down BATF, eliminating the Department of Homeland Security, and returning the constituent agencies like the Coast Guard back to their original executive departments. Ending the security theater at commercial airports would be another important step. Profiling works, ask the Israelis.
