An Aesop: A potential one – jury duty should never be taken lightly, as the detectives discuss in theorizing why the jury would acquit despite what they saw as an Open-and-Shut Case of a career criminal.
Caught on Tape ... well, not exactly on tape, but Friday and the forensics department determine that using a special kind of dust, visible only under the light of an ultraviolet lamp, will help connect experienced safe burglar Buckley to his crimes and put him away for good.
Excuse Boomerang: The safe burglar, Buckley, enjoys living high, with fancy cars and beautiful women, despite a modest income as a journeyman cabinet maker. Hence, why he committed the crimes.
Hollywood Law: The judge, scolding the jury because of a verdict to acquit a man who was in his opinion obviously guilty. Generally, this is frowned upon, even if the jury clearly got it wrong. Real-life examples are rare but not unheard of.
"The Reason You Suck" Speech: The judge minces no words that he not only disagrees with the verdict but that – in a gross miscarriage of justice being carried out – he claims the jurors are either dishonest or "complete morons."
Rogue Juror ... or perhaps rogue jurors, who somehow arrive at a not-guilty verdict, despite the case being open and shut. None of the jurors are found to have any connection to Buckley; they just simply didn't believe he was guilty or something.
