A Court Just Ruled Police Can't Ransack Your Phone Because You Went to a Protest

What Happened

In 2021, Jacqueline Armendariz Unzueta attended a housing protest in Colorado Springs. Police arrested her for obstructing a roadway, claiming she threw a bike at officers. What followed was not a routine investigation into that allegation. It was a sweeping digital dragnet.

Colorado Springs police obtained three warrants that, taken together, authorized access to virtually every corner of Armendariz's digital life and the data of a nonprofit that organized the protest. This week, a federal appeals court said that went too far.

The Three Warrants

The scope of what police sought was staggering:

• Warrant 1 authorized a search of Armendariz's home and the seizure of all her electronic devices.
• Warrant 2 authorized a search of data on those devices, including all photos, videos, emails, and text messages over a two month period, plus two months of location data. It also allowed keyword searches across years of data using 26 terms, including generic words like "bike," "assault," "celebration," and "right."
• Warrant 3 targeted the Facebook page of the Chinook Center, the nonprofit organization that organized the protest. Police demanded all posts, messages, and events from the organization's account, despite the fact that the Chinook Center faced no criminal charges.

A keyword search for the word "right" on someone's device means every text message, email, and document containing that word becomes fair game for law enforcement review. Applied over years of data, that is not a targeted investigation. It is surveillance.

The Ruling

In a 2-1 decision, the U.S. Court of Appeals for the Tenth Circuit reversed the lower court's dismissal of the lawsuit. The court "painstakingly picked apart each of the three warrants" and found them to be "overbroad and lacking in particularity as to the scope and duration" of the searches.

Critically, the court also ruled that the officers were not entitled to qualified immunity, the legal shield that typically protects police from civil rights lawsuits. The Tenth Circuit held that the officers violated "clearly established" law by obtaining such "facially deficient" warrants.

The case, Armendariz v. City of Colorado Springs, has been remanded back to the district court to proceed.

Why This Matters for Everyone With a Phone

The Fourth Amendment protects Americans from "unreasonable searches and seizures." But in practice, courts have often given police wide latitude to search digital devices, especially when a physical arrest has already occurred. Appellate courts rarely challenge the validity of search warrants, and even more rarely deny officers qualified immunity.

The Tenth Circuit's ruling pushes back on both fronts. It establishes that a protest related arrest does not give police a blank check to search years of a person's digital communications. And it holds officers personally accountable for obtaining warrants that any reasonable officer should have recognized as unconstitutional.

The Electronic Frontier Foundation, which filed an amicus brief alongside the Center for Democracy and Technology, Electronic Privacy Information Center, and the Knight First Amendment Institute at Columbia University, called the decision a "victory" for digital privacy rights.

The Nonprofit That Was Never Charged

Perhaps the most troubling aspect of the case was the third warrant. The Chinook Center organized the housing protest where Armendariz was arrested. The organization was never charged with any crime. Yet police obtained a warrant demanding its Facebook data, including private messages and event information.

The ACLU of Colorado, which represented both plaintiffs, argued this had a chilling effect on the right to organize. If attending a protest means your organization's private communications could be seized by police, fewer people will organize and fewer will participate.

A Pattern Worth Watching

This ruling comes at a time when digital surveillance of protesters is expanding. Law enforcement agencies across the country have used cell tower data, social media monitoring, facial recognition, and geofence warrants to identify and track people who attend demonstrations.

The Tenth Circuit's decision does not ban any of those tools. But it does set a boundary: warrants must be specific about what they are looking for and how far back they can reach. A keyword search for the word "right" across years of someone's personal data is not a targeted investigation. It is the kind of general warrant the Fourth Amendment was written to prevent.

The case now returns to the lower court, where the merits of the civil rights lawsuit will be argued. But the Tenth Circuit has already delivered the most important message: your phone does not become government property just because you showed up to a protest.
