John Giacalone typo in Q post (cap "I"). i think he might be /ourguy/ He was the lead field investigator for the FBI on the Shillary email case.
Six months later, the senior FBI agent in charge of that investigation resigned from the case and retired from the FBI because he felt the case was going "sideways"; that's law enforcement jargon for "nowhere by design." John Giacalone had been the chief of the New York City, Philadelphia and Washington, D.C., field offices of the FBI and, at the time of his "sideways" comment, was the chief of the FBI National Security Branch.
The reason for the "sideways" comment must have been Giacalone's realization that DOJ and FBI senior management had decided that the investigation would not work in tandem with a federal grand jury. That is nearly fatal to any government criminal case. In criminal cases, the FBI and the DOJ cannot issue subpoenas for testimony or for tangible things; only grand juries can.
Giacalone knew that without a grand jury, the FBI would be toothless, as it would have no subpoena power. He also knew that without a grand jury, the FBI would have a hard time persuading any federal judge to issue search warrants. A judge would perceive the need for search warrants to be not acute in such a case because to a judge, the absence of a grand jury can only mean a case is "sideways" and not a serious investigation.
As the investigation dragged on in secret and Donald Trump simultaneously began to rise in the Republican presidential primaries, it became more apparent to Giacalone's successors that the goal of the FBI was to exonerate Clinton, not determine whether there was enough evidence to indict her. In late spring of this year, agents began interviewing the Clinton inner circle.
