Williams explained all this on CoasttoCoast radio show one night not too long ago. It was scary to hear him then, guess this proves he knows what he is talking about.
Yes, he told the host, George Noory, that arrests in Canada were imminent, and he was obviously correct. He said this operation wasn't involving a handful of terror suspects, but a "hive", as in many handfuls. I hope that's all he's correct about, as I believe he says there are already suitcase nukes in the U.S.
God help us.
