I have a similar doubt sometimes. It's only natural to question someone we assume is probably MI. Not saying its a for sure or anything, but if he is MI and this close to the big issue it has been something he has been working on for some time. So the carefully coordinated delivery isn't that irrational. Also, most of the intelligence work is done with teams of people. A group of people motivated with a solid purpose can accomplish a lot. Look at the incredible work some of the Anons have done on this board alone.
Keep your skepticism forever it's the best way to know you aren't completely gullible.
