Sorry, but you greatly overestimate the ability of the courts to restrain the FBI. There are many examples of the FBI submitting false declarations to the courts, accessing password-protected files without a warrant, using improperly obtained evidence, and more. [1] Intelligence tools are pitched as counter-terrorism, and then used in whatever cases they feel like it. For example, the Stingray phone surveillance device, which the FBI loans out to be used by local police departments, without warrants. [2]. Or pretty much the entire Patriot Act. Of course the FBI wants the power to do this independently. And this is exactly how they go about obtaining this power.
