Having had a great deal of personal experience with the FBI and the channels and management they're required to use and satisfy, I can verify that it's entirely accurate that everything is down to the individual. It's exactly the same kind of bureaucracy people complain about in large companies, except that the very bare possibility of change we hold on to in large corporate environments is not present.

Working with that organization in particular will teach you very quickly about the kind of immense roadblocks that exist to even the more "moderate" of conspiracy theories. Not only are they beholden to absolutely everyone, they don't have time to make things up or bury facts. Obviously there are exceptions, but this and most other government agencies are just loose conglomerations of individuals doing a never-ending amount of thankless work with the reward of being scrutinized and accused of every possible crime at every possible turn.

I hold government and its agencies in no high regard, because people are people and we all suck in our own way, but suggesting conspiracy at certain levels is just laughable.
