That was just the standard, “it was not terrorism message”, or the “we may never know why he did it” message. Kind of pro forma…
Yes, the pro forma kneejerk FBI lie. It was way too early for them to know whether anything needed to be covered up but just in case something turned up they would already be on the right track.
Am I cynical and biased?
I don’t think so, I’ve seen Christopher Wray testify under oath quite a bit.
