The Texas test case experts worry Trump will use to limit dissident political speech

On July 6, 2025, Daniel Rolando Sanchez-Estrada got a call from his wife. She was in jail after attending a protest at a U.S. Immigration and Customs Enforcement detention center in Alvarado and was worried police might search their home in Garland. 

An hour later, Sanchez-Estrada loaded his car with various boxes of anti-government and anti-Trump literature, according to court filings. FBI agents waiting outside his house followed him to a nondescript Denton apartment, where he left the boxes. Dallas police officers then arrested Sanchez-Estrada on orders from federal agents. 

A year later, Sanchez-Estrada is now serving 30 years in prison for moving the documents 56 miles.

Sanchez-Estrada is one of sixteen people sentenced to a collective 562 years in prison for their connection to the Prairieland Detention Center protest — unusually harsh punishments that First Amendment experts around the country are concerned will have a “chilling effect” on political protest around the country.

“It doesn’t take a law degree to think that that seems like a completely draconian and disproportionate punishment for the conduct here,” said Katie Fallow, deputy director of litigation at Columbia’s Knight First Amendment Institute. 

Federal officials said protesters attempted to violently attack the facility. FBI Director Kash Patel repeatedly characterized protesters as an “antifa cell” after they shot fireworks and vandalized property, with one protester shooting and wounding a police officer. 

The characterization opened the door for terrorism charges after Donald Trump labeled antifa as a domestic terrorist group in a September 2025 executive order. While protesters repeatedly denied any connection to antifa, this case is the first that uses Trump’s executive order to enhance sentencing — an “unprecedented” move, according to Fallow.

“The concern is that the Trump administration will now use this as a test case to then go after other left-wing protesters, and that should trouble everybody across the political spectrum,” she said.

Legal experts interviewed by The Dallas Morning News are worried the novel use of domestic terrorism charges against protesters could present a blueprint for cracking down on dissident political speech.

Genevieve Lakier, a law professor at the University of Chicago who studies the First Amendment, said she’s worried about the administration’s effort to “transform” political expression into terrorism. 

“There’s this effort to think about it as terrorism or as conspiracy or as some other kind of non-speech crime,” she said. “That’s a real problem.” 

While there is no federal charge for domestic terrorism, many defendants were charged with providing material support to terrorists. This allows judges to hand down longer sentences under U.S. sentencing guidelines, and explains why many of the protesters are spending decades behind bars. 

Francesca Laguardia, a professor of justice studies at Montclair State University in New Jersey who studies terrorism prosecutions, said the trial’s outcome has more to do with the broad nature of the law.

“It allows for convictions that have very little to do with actual terrorist intentions,” she said.

Congress debated terrorism laws for years before passing The Antiterrorism and Effective Death Penalty Act in the late 1990s, because residents were concerned it might be used to criminalize protected conduct. 

“The threat that terrorism statutes pose to First Amendment activity has always been a concern,” she said.

The law, she said, was initially crafted to prohibit associating with foreign terrorist organizations or committing high-level crimes linked to terrorist activity and acts of extreme violence. But the Prairieland case signals a change in how “aggressively the DOJ is pursuing political activity,” Laguardia said.

The result is unfortunate for people wishing to attend protests, Laguardia said.

“They have to think about who they are standing next to and who they’ve been communicating with up until that point,” she said. “It’s concerning how much that might chill people who really mean to be involved in purely peaceful protests.” 

Federal leaders and prosecutors were clear that they believed defendants’ actions escalated beyond a typical protest — and deserved to be punished as such. 

The July 4 protest began as a noise demonstration, with protesters setting off fireworks in solidarity with detained immigrants. Protesters across the country decried the Trump administration’s sweeping immigration enforcement that led to arrests — including the Prairieland protesters, who decried detainments in North Texas.

What began as a peaceful protest escalated as demonstrators vandalized government property, and became violent when Benjamin Song shot and wounded a police officer. 

“The calculated violence carried out by these Antifa cell members at Prairieland was an assault on law enforcement and an attack on the rule of law itself,” David J. Venturella, acting ICE director, said in a statement after the sentencing. 

Kevin Golberg, a First Amendment expert at nonpartisan foundation Freedom Forum, said the case presents concerns that protesters were unduly punished for their political views. But he added it was important to review constitutional doctrine when evaluating potential First Amendment infringements.

“I specifically want to remind people that the words of the First Amendment do not protect assembly; they were to protect the right of the people to peaceably assemble,” he said. 

Even with the clear violations of the law, some experts are worried the punishments are disproportionately harsh for the crimes committed. 

Jason Blazakis, a professor at the Middlebury Institute of International Studies and executive director of the Center on Terrorism, Extremism and Counterterrorism, warned it’s “dangerous” that someone who committed vandalism could be viewed as a terrorist under the current law.

“Destroying a $50 camera doesn’t really meet my commonsense litmus test of somebody who is engaged in terrorism,” he said. “There’s a lot left to interpretation here.”

A variety of defendants — including Sanchez-Estrada — have already appealed their sentences. But as they move to the next step of the process, experts warn the initial sentences set a dangerous precedent for punishing left-wing political protest.

“What we’ve seen with the ICE protest is a concerted effort by the Trump administration to intimidate and use the threat of legal sanctions to try and kill protests,” Lakier said. “It wants there not to be protest and not to be dissent — that’s what it’s clearly signalling.”

Brian Bouffard, an attorney for protester Zachary Evetts, said his client has already started the appeals process. More concerning than the decades his client now faces in prison, he said, is the potential for similar punishments to be recreated around the nation. 

‘The government now has a blueprint to use that kind of law against and only against people who are ideologically opposed to the current administration,” he said.
