The FBI does not have to tell the public one bit of information about their investigation. Sorry.
Why would you ever think that they had to?
Heck, they don't even answer to congress, same as Holder, Jarrett, Obama, Obama, DHS, democrats.
Even Saudi terrorists get set loose and Muslim Brotherhood member Jarrett passes out candy while Obama does as he is told so he will not feel the brunt of Muslim Law.
Well, the Keystone Cops apparently waited 2 days to release the photos.
