Are you claiming the fbi has never been called to testify before Congress? or are you claiming that it didn't happen enough? or that it didn't happen for the things you personally wanted it to happen over?
these are very different situations, and it appears you wish to defend the motte and get the bailey for free?
No? I wouldn't consider the FBI to be an "unaccountable organization".
I never said all government organizations are unaccountable? Just that (practically-speaking) some organizations are unaccountable because they rarely (or never) are called to account by those who are supposed to hold them accountable. This could be due to them simply being a low-stakes organization that demands very little attention, for all I know!
Interesting that you call out a specific fallacy whilst bringing your own strawman into play!
