Recent reports of alleged “narco-banners” warning Americans to steer clear of Mexico’s Los Cabos region have ignited fears about cartel intimidation, despite local officials denying their existence. These supposed messages, attributed to La Chapiza, a faction of the notorious Sinaloa Cartel, threatened violence against U.S. visitors and residents in the area. While photos of these banners have spread rapidly on social media, authorities in Baja California Sur claim no physical evidence has been found.

Joe Peters, the District Attorney of Wyoming County, Pennsylvania, who has experience in the White House drug policy office during the administrations of Bill Clinton and George W. Bush, shared his insights with Fox News Digital. He noted that whether or not the banners in Cabo were actually found, the strategy aligns with a long history of cartel “narco-terrorism.”

“When a cartel of this magnitude and sophistication is operating right on our doorstep, it demands serious attention,” Peters stated. “It’s a clear warning to both U.S. and Mexican governments. These cartels wield power through threats and intimidation, much like the mafia used to do.”

Public displays of intimidation, known as “narcomantas” in Spanish, have historically been a tool for Mexican cartels. These large banners, often placed prominently on bridges or in public squares, are used to issue threats, stake claims, or provoke rival groups.

Public “narco -anners,” or narcomantas, have long been used by Mexican cartels as propaganda tools, with the large signs draped across bridges or hung in public plazas to issue threats, claim territory or taunt rivals.

Peters said reports of such banners should be taken seriously given the proximity to America’s borders.

“When you’re dealing with a cartel that serious and that close to our border, we have to take it seriously. Add to that the number of Americans traveling to Latin America for business or pleasure — it’s a ready stock of potential victims for extortion,” he said.

Peters, who served in senior roles in the White House’s Office of National Drug Control Policy under Presidents Clinton and George W. Bush, said the current threats echo the global cartel tactics he saw firsthand.

In the 1980s and ’90s, Colombia’s cocaine cartels controlled entire regions through intimidation, corruption and fear tactics that are nearly identical to what’s now unfolding in parts of Mexico.

“Their strategy is simple: if they can control the levers of power in a nation through intimidation, then they control the nation,” Peters said. “They assassinate police, judges and journalists, and they use fear to rule, the same way authoritarian regimes do.”

The difference today, he warned, is proximity. This time, the violence and instability are unfolding just beyond America’s southern border, in places millions of U.S. citizens visit each year for vacations and business.

That closeness, Peters said, makes Americans prime targets for extortion, kidnapping and terror.

“My advice is simple: don’t go unless you really need to,” he said. “Be cautious, and stick to places with an established record of safety.”
