The Rule of Non-Interference states that aliens cannot interfere in mankind's affair unless The Call is given so that consultation with a human results in action. Thus, for instance, ZetaTalk, composed of thousands of pages now, answering thousands of questions from humans, which are considered The Call. In that our arrangement with MJ12 was allowed by the Council, to balance a trick maneuver the Service-to-Self aliens visiting the US military just ahead of the Earth Vote which resulted in a "not conscious" rule re visitations, our open discussions with MJ12 were allowed. Balancing the environment for Service-to-Others and Service-to-Self deliberations among 3rd Density entities is not new, as for instance the giant hominoids from the 12th Planet were put into quarantine, removed from Earth, to effect this balance.
Even without the New MJ12, the Enron revelations might have occurred via contactees. If a contactee is distressed, wringing their hands, over a situation, and give The Call, and we inform them as a result of what information might be most damaging, when given to whom, then a contactee might have effected the Enron scandal. As it happened, the humans within the New MJ12 effected this, by a computer snafu whereby information supposedly deleted was instead mailed and broadcast. This was done by human hands, and thus we, the Zetas, did not interfere.
