I think leaving behind one's wedding ring and 95% of one's meager life savings a few hours before one's short-rifle is found hidden with one's fingerprints on it in one's seven-story, on-the-motorcade-route, place of work is consciousness-of-guilt-in-advance

were matched to said short-rifle to the exclusion of any other rifle in the world.
You mean the short rifle you cannot prove killed anybody or was ever in the possession of your favorite suspect?
