Paris Museum Heist Shines Spotlight on Security Concerns

Entering the world’s most-visited museum in broad daylight, grabbing eight pieces of priceless historical gems and vanishing into Paris traffic on humble scooters may seem like the most audacious of crimes, executed for international notoriety and subsequent movie adaptations.

Specialists who observe trends in global cultural theft, however, see the recent heist at the Louvre as a more practical matter: the latest in a series of quick-hit thefts focused more on the material value of valuable gems or metals than the historical importance, continuing a trend that has emerged over the last ten years in Germany, Britain and the US. The location, they suggest, would have been of secondary concern to the thieves.

“You may ask why thieves who want to take expensive jewellery are entering a globally renowned museum rather than a Cartier store,” stated an expert in art recovery. “It's straightforward: it’s because these days a high-end boutique is more secure.”

A series of violent retail store thefts indicate that many outlets have strengthened their security in recent years, with armed guards on their premises and merchandise no longer shown overnight. Museums, on the other hand, look more exposed, in part because of the in-built reason of being public-facing institutions in historic buildings, and partly the financial situation in many developed nations.

“Since Covid, governments across the globe have reduced spending on law enforcement and the culture sector,” noted Marinello. “With criminals entering the Louvre, it shows how at risk our institutions have become. This is a difficult time to be a museum.”

The robbery of the items – including jewelry pieces made up of eight sapphires and hundreds of gems, the crown of a historical figure containing thousands of diamonds and a hugely valuable crown once possessed by Napoleon III’s wife that the thieves left by the roadside on their way out – has inevitably drawn comparisons with the 1911 theft of the Mona Lisa from the same museum, performed by the worker the thief.

Better comparisons may be the 2019 theft of jewellery from Dresden’s Green Vault Museum worth over €113m, the theft of a £4.75m valuable object from a UK landmark the same year, the 2017 robbery of a large gold coin from a European museum or even a series of thefts of collector items from American institutions.

“There’s a simple pattern here,” explained Marinello. “Break in, take items, and dismantle them as rapidly as possible.”

If the items were to remain intact, specialists say, the criminals would struggle to find a buyer. “There’s no way to sell something as recognizable as the museum's gems on the licit market”, commented Lynda Albertson of the a relevant organization.

“They would be immediately recognised, particularly given the cultural authorities has released images of the items. Even a individual buyer or an sales venue would want to see documentation confirming proper ownership before touching such striking pieces.”

In the past, institutions were often reluctant to announce publicly about the loss of well-known art pieces and would remain quiet out of shame. Now, as cultural robberies are more widely publicised, the keeping and sale of taken items is dangerous for any lawbreaker.

“If you steal a Picasso, it has to remain intact or it becomes valueless, and you have to devise a scheme to keep it in hiding, maybe by moving it among difficult criminal actors,” noted Marinello. “There's ongoing risk to the danger of an accomplice telling the police to cash in a reward.”

For comparable factors, an art detective said it was highly improbable that the robbery had been commissioned. “Commissioned theft is something from Hollywood movies,” he said. “Nobody would touch this. It's global news and in all the newspapers. If you buy this, if you get caught, you end up in prison. You can't display it to your friends, you cannot bequeath it to your children.”

Modifying taken items by melting down or re-cutting does reduce the worth. When it comes to gems, it also comes with considerable risk because modern cutting techniques give gems a larger and brighter surface area, and antique-cut stones would either attract notice or barter the price down for a coverup.

Importantly, however, melting down or re-cutting eliminates the proof of the crime. “My guess is that the robbers will try to take the stolen goods to locations with diamond expertise like a country, India or even as close as Antwerp, and find someone to remove the gems,” suggested Marinello.

The heist at the Louvre has already brought up concerns about protective steps at the institution, with a unauthorized official review expected to be released soon criticising “significant” and “ongoing” slow progress in modernizing equipment and noting that security cameras were lacking in multiple areas. But security experts say showing precious items in historic buildings with a steady stream of visitors comes with dangers that are not possible to remove entirely.

“Older structures are more difficult to protect,” explained an art crime professor. “They often have large accessible windows that makes it easy for thieves to get away, and there may be preservation laws in place that mean you are unable to install them with proper bulletproof glass.”

The most solid protective measures for structures should be conceptualised “as a stronghold”, noted a security advisor. “There should be multiple levels to repel attackers.”

Contemporary structures are equipped with state-of-the-art surveillance systems or integrated seismic detectors that raise alarm about a broken glass in real time, but historic institutions may be reluctant to alter their appearance. Detection devices can be hard to install to decorated surfaces. Motion and sound detectors may also have to be disabled during the day as crowds stomp through a museum.

The timing of the Louvre raid, which occurred between 9.30am and 9.40am in Paris, was common of modern robberies, Stürmann said. “It's logical why robberies tend to happen at either start or end of day. It’s often when security rotate and before the museum is full of visitors who actually act as additional security staff.”

Advances in technology may have thrown up new gadgets that can raise the alarm more quickly and effectively, but it has also given thieves new methods with which to bypass protections. In Paris, the robbers accessed the museum’s upper level with a vehicle-mounted ladder and cut through a window with a battery-powered disc cutter.

Elaine Sciolino said the discussion in the country about the historic structure had mostly focused on visitor management in the past decade, and not as much on protection.

The institution has an in-house brigade of about fifty permanent emergency personnel, but their mission is mostly to safeguard the collection from blazes and water damage. “There is no rapid-response unit,” Sciolino said. “In the end, the security of the Louvre all depends on political will and money, and currently the nation lacks sufficient resources.”
