I do believe that this is one of those situations that keeps us fascinated in finding the truth as to how extensive the plot was and who was involved. However, I do not believe that we will ever confirm that it was Mike O'Laughlen who reportedly went to Stanton's home -- and even if he did, will we be able to confirm what his intentions were? I believe that it was Mike Kauffman who first suggested that O'Laughlen went there to warn the Secretary. That's as good a guess as any, unless descendants of the O'Laughlen's can pull a magic letter or document out of an old trunk...
