I have suspected more than just three involved in the vague meeting in Andy’s office, except only three names were mentioned.
As sundance noted, for the (so-far) disclosed actions to have happened, there is no way Bill Priestap could not have been NOT in the loop.
If he is not directly involved, at least a tacit understanding is to be suspected by us (people from the outside).
Where is the list of names from McCabe’s F@ck Flynn meeting?
IIRC three were 30.attedees.
