This statement is emblematic of the author's approach. The author states that he has experience in field operations and knows the rules governing this sort of undertaking. A couple of analytical points.
First, note that the author puts the case together very cogently... but, he does not reveal anything not already exposed in the media. The timeline is well and accurately constructed but it is essentially skin and bones; no meat of revelation ... It is all open-sourced.
The second point is captured in the above quote: it assumes a series of coincidences that came together in the face of poor planning and ineffective leadership.
An experienced field operative survives by one hard and fast rule: there are no coincidences. If it works out in the nonce that a coincidence did occur, nothing has been risked. The opposite can prove terminal.
I choose not to believe that, conveniently, Bruce Ohr's wife just happened to work for Fusion GPS which provided a lifeline to the Steele/FBI conduit AFTER the FBI severed contact with Steele. Senior DoJ legal counselor, Bruce Ohr, pulled up his bootstraps and filled the void created by the broken communications link.
But wait! The FBI claimed that they had to cut off contact with Steele because of his insecure media leaks. Why would a high level cutout like Bruce Ohr become necessary? ...and there sat Ms. Convenience - Nellie Ohr - in direct contact with Steele and with the best blue ribbon channel to the FBI through her husband, a high level DoJ official.
The FBI was no longer in contact with Christopher Steele! They were in contact with a senior DoJ official who knew someone (his wife) who knew Steele. That is of course the purpose of a cutout: to provide credible deniability as well as an additional layer of security.
So who was the mysterious HAND behind the scenes directing all this subterfuge? Was it Clapper? ...Brennan? ...Susan Rice? ...HRC? Mr. Untouchable himself, Barak 0bama? Alas, we don't suffer the revelation.
I can propose a credible candidate; I cannot state his name, but his initials are George S0r0s.
One coincidence is very possible. Seventeen is next to impossible. I can't do the math but it's similar to the 'one grain on the first square of a chessboard... then double it next square and again and again... or in this case 17 times. 1, 2, 4, 8, 16, 32, etc...
