Navy SEAL convicted for plotting explosive attack at San Diego protest

 January 14, 2026

A federal jury in Albuquerque, New Mexico, has convicted Gregory Vandenberg, a former Navy SEAL, of transporting fireworks across state lines with the intent to use them as explosives against police during the "No Kings" protest in San Diego last year.

The conviction came on Monday after a five-day trial, with Vandenberg now held in custody awaiting sentencing, which could carry up to 10 years in prison, according to the U.S. Attorney’s Office. Evidence presented by prosecutors revealed his plan to travel from El Paso, Texas, to California for the June 14 rally, targeting law enforcement officers. FBI agents also uncovered extremist symbols and messages in his possession, pointing to neo-Nazi beliefs and hostility toward specific groups.

The case has ignited sharp debate over the boundaries of free expression and the dangers of violent intent. Critics of progressive policies often point to such incidents as evidence of unchecked extremism festering in society’s fringes. What’s clear is that Vandenberg’s actions crossed a legal line, turning personal grievances into a public threat.

Tracing the Path to Arrest

Details from the trial paint a troubling picture, as prosecutors showed Vandenberg stopped at a travel center near Lordsburg, New Mexico, on June 12 to buy six large mortar fireworks and 72 M-150 firecrackers meant to mimic gunfire. As reported by AP News, he openly bragged to a store clerk about his explosives knowledge and special operations background, revealing his plan to harm police at the upcoming demonstration. Store employees, alarmed by his behavior, noted his license plate and alerted authorities.

Vandenberg’s arrest came swiftly on June 13 while he slept in his car at Davis-Monthan Air Force Base in Arizona. He claimed to FBI agents he was traveling for work and visiting friends in Phoenix, a story that crumbled under scrutiny since he had no stable employment and lived out of his vehicle. The contradiction only deepened the case against him.

Investigators also found clothing and items in his car bearing anti-Israel slogans and neo-Nazi symbols, including a flag for a militant group called the Caucasian Front. A Latin phrase translating to a call for destruction further underscored his radical views. This wasn’t mere rhetoric; it was a prelude to planned violence.

Disturbing Beliefs Fuel Dangerous Plans

Prosecutors highlighted messages on Vandenberg’s phone showing deep anger toward political figures and unfounded conspiracies about government control by specific ethnic groups. His phone’s home screen bore a Taliban flag, a chilling signal of his ideological leanings. These details reveal a man consumed by hatred, willing to act on it.

At the travel center, Vandenberg wore a T-shirt he designed with a term meant to signify the destruction of a particular group, as he explained to the clerk while urging them to join his cause. Such boldness in public spaces shows a reckless disregard for consequences. It’s a stark reminder of how toxic ideas can push someone toward real-world harm.

Acting U.S. Attorney Ryan Ellison captured the heart of the matter, stating, “People in this country are free to hold their own beliefs and to express them peacefully.” That freedom, however, stops at violence, and Ellison’s words affirm the government’s resolve to prosecute those who weaponize their views. “Vandenberg intended to turn explosives into a tool of intimidation,” Ellison added, a line that cuts to the core of this case.

Balancing Rights and Public Safety

The verdict against Vandenberg lands at a tense moment when debates over free speech and public safety clash with increasing frequency. Many worry that silencing unpopular opinions sets a dangerous precedent, yet few can argue with cracking down on clear threats to harm others. The line must be drawn somewhere, and this case seems to mark it firmly.

Look at the broader picture, and you see a society grappling with how to handle fringe ideologies without fueling them further. Heavy-handed responses can backfire, turning extremists into martyrs for their misguided causes. Still, ignoring credible threats like Vandenberg’s isn’t an option either.

His plan to attack police at a protest wasn’t just a thought crime; it was a calculated step toward chaos. Law enforcement, often caught in the crosshairs of political unrest, deserves protection from such schemes. The conviction sends a message that intent to injure won’t be tolerated, no matter the underlying belief.

A Wake-Up Call on Extremism

Vandenberg’s case exposes the underbelly of radicalization that thrives in isolated corners, far from the mainstream discourse. It’s not enough to dismiss such individuals as lone actors when their actions could endanger countless lives. Society has to confront how these ideologies take root and spread.

Some might argue the focus should be on rehabilitation over punishment, but when someone stockpiles explosives with a clear target in mind, mercy feels like a luxury. The priority must be safeguarding communities from those who’ve already chosen violence as their voice. That’s not oppression; it’s common sense.

Ultimately, this conviction stands as a necessary stand against turning protests into battlegrounds. While the right to dissent remains sacred, twisting it into a justification for harm undermines everyone’s freedoms. Let this be a cautionary tale for those teetering on the edge of similar paths.
