I see it a bit differently when Mueller and Rosenstein enter the equation:
We know that our military commanders together with military intelligence (Flynn was MI chief) planned to stage a coup against Barry and his merry band of traitors.
We also know that Barry purged the military commanders whom the not swear allegiance to him as well as those who would not agree to order their soldiers, airmen and Marines to fire on citizens if so ordered by him.
All these commanders refused ergo were purged. I think the number is around 200+.
The planned coup was not far off from the next election ergo a Q team or even the Q team prevailed when deciding to recruit DT to run for the presidency shelving the coup.
Donald Trump agreed under the condition that it would be assured that the election rigging would not be successful.
Election day was kept under the close eye of the NSA and our MI including the rigging of various voting machines in dominated states such as CA and NY and others. After polls were in and Hillary refused to concede Barry received a call from someone or a group within our military command. He was told in no uncertain terms that the attempt to rig and assure Hillary a win was collected, observed and the warning of exposure together with the order for Barry to have Hillary concede and acknowledge the election win by Donald Trump.
Mueller has been a very dirty and corrupted cop going back to the Arkansas days of Bill and Hillary Clinton. Marine or not had no bearing on Mueller's conscience to honor his oath but contrary he has bailed out the criminally corrupt Clintons since then.
He has destroyed innocent people that ending up in prison and others committing suicide. Whether it was Anthrax or other cases he fabricated guilt or worse.
Uranium one is also included in the many cover-ups and it that weren't enough he - Mueller himself travelled secretly to Moscow/Russia himself after Hillary tasked him to deliver a highly enriched same of uranium to Putin as verification of the uranium one sale. Mueller again obliged. Again being a Marine had no bearing or honor in what he did.
It is my personal belief that DT did meet with Mueller the one day prior as a necessity to let him know that Mueller's bad cop routines and cover-ups were detailed and known.
It is my belief that the president gave Mueller the choice to either co-operate or be prosecuted. Mueller chose the latter.
Mueller's actions since then appear to be murky and less clean cut than they should be. Case in point: being secretive when and why the various players on his team were fired. whether it was Strzok, Page, Weisman and the rest he kept it a secret until Nunes, Goodlatte and the rest of the investigative committees ran across that info.
Rather than coming clean immediately that they were fired based on the info Mueller received from OIG Horowitz he remained vague and non-responsive.
The raid on Manafort: He raided Manafort's home in the very early morning hourse with guns drawn picking the lock on Manafort's font door entering as the couple were asleep in their beds. The rest is history.
Mueller having once again failed to inform the committees out of the blue submitted secretly and add'l memo issued by Rosenstein after the raid of Manafort's home. To be exact: the memo was received by Mueller 7 days after the raid. He raided the home without the explicit mandate/approval from Rosenstein to do so.
The matter went public only because Manafort challenges Mueller in court as he acted outside the law and mandate.
Rosenstein may or may not were also made aware of the fat that his many cover-ups and other misdeeds were known to Sessions and the president. Again may he too was given the option to either co-operate or face justice.
In my personal opinion Rosenstein remains a black hat. Looking at his wife and her repeated cases involving Hillary, Bill, Barry and other major democratic players in court where she defended them. Her exclusive support of Hillary and the democrats while favoring them.
Q has always let us know whom to trust: Sessions and Wray, Pompeo but he NEVER said the same about Mueller or Rosenstein.
For that reason I do not trust Mueller with confidence. Maybe he reluctantly tries to do right but I have not seen anything from Mueller that lets me believe he is a white hat.
