"Let me say, up front, that I do not believe the vast majority of Masons have any knowledge of these activities, nor anything to do with them. I feel it would be grossly unfair to blame them for this. We did reveal how Masonic oaths could be used to conceal damaging secrets. However, that doesn't change the fact that most Masons are good, kind-hearted people who do not want to participate in anything nefarious."
Masons are prohibited from committing felonies, doing such negates membership. Also, there is no burden to keep the secret of another Mason should he do such. The dark minded seek shadows to hide. Where there are notable structures, and light, shadows are also present. By shining light from all angles, the shadows receede!
