Really, you should take that supposed FBI agent with an entire shaker of salt. There's no way of verifying that he (or she) is legit, and the fact that they hit every single hard-right talking point leads me to believe that this is just some /pol/ troll. I mean, the poster manages to tie in a CFR one-world conspiracy, George Soros (funding all levels of government, apparently), and some bizarre point about "Blacks are inherently violent and impulsive...and they can be, for lack of a better term, domesticated." It doesn't read like anything an actual FBI employee would write.
I understand that, I said the same thing. I'm just saying that there isn't really a reason for Comey to have made the statement he made unless he wanted to leave the door open for later... say after a new AG is appointed early next year.
