In a recent bizarre occurrence out of Australia, reporter Peter Steer was on his way to cover a shooting when the suspect (Jule Brook) flagged him down. Initially unaware of who Brook was, the man then tearfully confessed to the shooting. Yet in a few moments his temperament changed and he then carjacked Steer's vehicle. Shortly thereafter he crashed it into a gasoline tank and tried to acquire a cigarette lighter - apparently with the intent of some impromptu arson activity before police could stop him.
The image below was taken as Mr. Jule Brook was entering and stealing Steer's vehicle. Note that his expression is one of a sincere, but suppressed smile. Smiling, even when partial or suppressed - if there are elements of sincerity present in such an out-of-context scenario - this should always raise concerns (when the smile is suppressed as it is in this and similar scenarios - it's akin to the psychology of duping delight). Of course Brook had just confessed to a shooting (in which he believed he had committed a murder, although his victim survived). Blood was literally on his hands and he had been crying a moment before. Now with the same gun he allegedly used in the first crime, announces his full intent to steal Steer's ride - and his expression has changed to a suppressed, sincere smile. This extreme emotional volatility is also another highly significant red flag.
