0:00 The air inside the Antwerp Diamond Centre vault is perfectly still.0:05 It is the night of February fifteenth, 2003.0:09 Ten layers of security stand between the outside world and one hundred million dollars in diamonds.0:18 And every single one of them is silent.0:21 The Doppler radar, the seismic sensors, the magnetic field… all defeated.0:28 The heist of the century is underway, and nobody knows.0:33 Last week on "Almost Perfect," we saw a meticulous plan undone by a single, critical miscalculation.0:42 This week… we see a plan so flawless that its failure came not from a brilliant detective or a high-tech alarm, but from a piece of garbage thrown out of a car window.0:56 It's a masterclass in audacity.0:59 The target was legendary.1:01 The Antwerp Diamond Centre wasn’t just a building with a safe; it was a fortress inside the diamond capital of the world.1:12 Its vault was protected by security so advanced, it was considered impenetrable.1:19 Infrared heat detectors, motion sensors, and a lock with one hundred million possible combinations.1:28 And behind all that, one hundred sixty deposit boxes belonging to the world’s wealthiest diamond merchants.1:37 To rob it was not a question of force.1:41 It was a question of art.1:43 And the artist was Leonardo Notarbartolo.1:46 He and his crew, later nicknamed the "School of Turin," approached the problem with breathtaking patience.1:56 For years, Notarbartolo posed as an Italian diamond merchant.2:01 He rented an office in the building.2:04 He did small deals.2:06 He made friends.2:07 He became part of the background noise, just another face in the district.2:14 But all the while, he was studying.2:17 He learned the schedules, the routines, the people.2:21 He learned the vault.2:23 Using a tiny camera hidden inside a fire extinguisher, he filmed the guards as they opened the door, capturing the combination.2:34 He and his team built a full-scale replica of the vault to practice on, learning its every secret.2:43 They figured out how to bypass the magnetic field on the door.2:49 They discovered that a layer of hairspray could temporarily blind the infrared heat sensors.2:57 They were not just thieves.2:59 They were engineers.3:01 On the night of the heist, everything went according to plan.3:06 They entered the building, navigated the corridors, and arrived at the vault.3:13 They used a custom-made key they had duplicated.3:17 They dialed in the combination they had stolen.3:21 They disabled sensor after sensor.3:24 And then they were inside.3:27 For hours, they worked, emptying one hundred twenty-three of the one hundred sixty vaults.3:35 They filled their bags with uncut diamonds, gold, cash, and jewelry.3:41 Then they cleaned up their tools, sealed the vault behind them, and simply… walked away.3:48 No alarms.3:49 No witnesses.3:50 They were ghosts who had just pulled off a one-hundred-million-dollar score.3:57 The plan was perfect.3:59 The execution was perfect.4:01 The cleanup was a catastrophe.4:04 On the drive away from Antwerp, one of Notarbartolo's accomplices, a man known as Speedy, began to panic.4:13 His job was to burn the bags of evidence.4:17 Instead, he pulled over on the E19 motorway and just… threw them into the woods.4:24 Inside one of those bags was a half-eaten salami sandwich.4:29 And on that sandwich was Leonardo Notarbartolo's DNA.4:34 Alongside it were receipts, business cards, and surveillance notes that laid out their entire operation.4:43 The lesson here isn't about building a better vault.4:47 The vault was already a masterpiece of defense-in-depth.4:52 The lesson is about the one variable you can never fully control: the human element.5:00 You can account for every sensor, every camera, every lock.5:05 But you cannot account for a moment of panic on a dark highway.5:11 The most sophisticated plans are always vulnerable to the simplest failures.5:17 Notarbartolo’s crew defeated a hundred-million-dollar security system.5:23 But they were defeated by a sandwich.5:27 The greatest weakness wasn't in the technology.5:31 It was in the trust that one man wouldn't crack under pressure, AFTER the job was already done.5:39 And that is a flaw no amount of planning can ever truly fix.
