Who contrils the DOJ gate where everything is to be recorded and forwarded? If you sent a letter to POTUS, how do you know that letter will actually get to him? Same goes with DOJ, they still have black hats that run the day to day operations, a place where the mail man has more power than the AG or his assistant. Is RR a good guy or the bad guy? The CF investigators sent in the product 3 times, what does that tell?
Never know what's in the dark until you shine or turn on the light!
