Schweitzer says he was joking but he gave an awful lot of details for a joke.
The corrupt ALWAYS succmb — eventually — to the ego-driven need to share their evil deeds with others.
When they do, they invariably say enough to hang themselves, but will ALWAYS claim “Oh, that was just a joke”, or “I was only kidding” if a record of their boasting ever gets any press.
Between me and YHVH, such caims are a desperate, paper-thin foil offered as a last-ditch effort to dissuade a serious investigation into the underlying substance of the bragging.
Since this is the established pattern — repeated over, and over, and over again throughout human history — these boasts should ALWAYS be taken as truthful records of actual events, and investigated to the Nth degree with an eye toward full, and complete prosecution under all applicable laws.
In brief: when evil men brag about buried bones, go dig up the skeletons, drag the perp into court, prove his guilt, read the sentence, and hang ‘em high.
If he was joking, then he shouldn't have to worry about any witnesses testifying against him.
Assuming of course that our government actually has the backbone to call him on it.
