I'm actually quite on the fence. It does seem to me to be conceivable that the FBI would pretend to be outraged when they are not.
I really don't have enough information and I don't trust anyone.
Of course they're outraged, in the same way that a serial burglar is outraged when they discover that someone's backdoor, which has been wide open for years, is suddenly locked. What's their outrage got to do with anything?
