I don't believe in the deep state, or don't want to, or am not yet convinced of its existence but as someone who has conducted complex multi-year investigations, including FISA matters, I am hard pressed to buy into making multiple mistakes in reports, let alone documents submitted to the courts.
It is troubling, at the very least, and I have a hard time believing that (multiple) errors, (including those of omission), can be overlooked not only by experienced and otherwise competent agents, but by the supervisory staff when it deals with matters of such delicacy and import.
I never felt that winning in court was worth perjuring oneself for and I loathed those who did so. To me, these "errors" may rise to the same level although I am reluctant to make that judgment.
Honest errors happen, but as Ian Fleming so aptly said:Once is happenstance. Twice is coincidence. Three times is enemy action.
