Minneapolis Police Scanner Encryption: An Accountability Crisis Five Years After George Floyd
On May 25, 2020, Minneapolis Police Officer Derek Chauvin murdered George Floyd. The MPD press release that followed claimed Floyd died from a "medical incident." Witness video contradicted this, sparking a global reckoning. Now, nearly five years later, Minneapolis has encrypted all police radio communications, eliminating another tool for independent verification of police accounts.
The context that cannot be ignored
Any discussion of Minneapolis police transparency must begin with George Floyd. On May 25, 2020, Minneapolis police released a statement titled "Man Dies After Medical Incident During Police Interaction." It claimed officers responded to a forgery call and that Floyd appeared to be suffering "medical distress."
The statement never mentioned that Officer Derek Chauvin had knelt on Floyd's neck for 9 minutes and 29 seconds.
Only because of witness video from 17-year-old Darnella Frazier did the world learn what actually happened. Without that independent documentation, the MPD's sanitized version would have become the official record.
The press release that sparked global protests
MPD's initial statement claiming Floyd died of a "medical incident" is now recognized as one of the most consequential police communications failures in American history. The gap between official police statements and documented reality changed the national conversation about police accountability.
Minneapolis encryption timeline
Hennepin County First to Encrypt
Hennepin County Sheriff's Office becomes the first Minnesota agency to encrypt radio communications.
George Floyd Murdered
Derek Chauvin kills George Floyd. MPD press release claims "medical incident." Witness video reveals the truth.

Department of Justice opens civil rights investigation into Minneapolis Police one day after Chauvin's conviction.
DOJ Findings Released
DOJ finds MPD used excessive force, discriminated against Black and Native residents, and violated First Amendment rights of protesters.
State Settlement Agreement
Minnesota Department of Human Rights settlement agreement approved, mandating police reforms.
City Council Approves Federal Consent Decree
Minneapolis City Council votes 12-0 to approve DOJ consent decree mandating extensive reforms.
Encryption Testing Begins
Minneapolis Police begins testing encrypted emergency dispatch channels.
Full Encryption Implemented
Minneapolis becomes the largest Minnesota law enforcement agency to fully encrypt all 911 police radio traffic.
Trump DOJ Withdraws from Consent Decree
Four days before the five-year anniversary of Floyd's murder, the Trump administration withdraws from federal consent decree.
St. Paul Encrypts
St. Paul Police Department follows Minneapolis with full encryption.
The accountability paradox
MPD encrypted its radios while carrying every item on that list:
- The same department that released a false press release about George Floyd's death
- Under investigation for discriminating against Black and Native residents
- Found to have violated First Amendment rights of protesters
- Facing a federal consent decree (later withdrawn)
- Still under state human rights agreement
- With a Community Commission on Police Oversight plagued by backlog and transparency issues
The timing raises a question officials haven't answered directly: if the goal is protecting victim privacy and officer safety, why did it take nearly five years after George Floyd's murder—and only after a federal consent decree was approved—to act?
Community Response: "They've Taken a Tool Away"
Minneapolis has a long history of police accountability activism. Community leaders have been direct about what they think encryption means.
"They've taken a tool away from the public to be able to monitor their actions and activities."Nekima Levy Armstrong, Civil Rights Attorney and Former Minneapolis NAACP President
Levy Armstrong has been a prominent voice for police accountability in Minneapolis since 2005. She founded the Community Justice Project, served as president of the Minneapolis NAACP, and co-chaired the mayor's Community Safety Work Group after Floyd's murder.
"Any time that you're reducing a transparency function in a place where there is not a high degree of trust between certain communities and the police... I think that it would make any community that's sort of reeling worried about, 'What is this police department going to do?'"Prof. Emmanuel Mauleón, University of Minnesota Law School
Operation Safety Net: the surveillance context
Radio encryption didn't happen in a vacuum. After George Floyd's murder, an MIT Technology Review investigation revealed "Operation Safety Net," a surveillance program that targeted civil rights activists and journalists across the region.
Social Media Monitoring
Police used software to scour social media platforms, building profiles on protest organizers.
Cell Phone Tracking
Law enforcement tracked protesters' cell phone locations, mapping their movements.
Facial Recognition
Widespread use of facial recognition technology to identify individuals at demonstrations.
Journalist Targeting
Police detained and photographed credentialed journalists, uploading their data to surveillance systems.
Federal Helicopters
Customs and Border Protection helicopters monitored protests from high altitudes to avoid detection.
Google Location Data
Police obtained geofence warrants from Google to identify protesters.
Since George Floyd's murder, Minneapolis law enforcement built out one of the most aggressive public surveillance programs in the country while cutting off public access to police communications. Radio encryption fits the same pattern.
Impact on Twin Cities journalism
A coalition of Twin Cities news outlets, including the Star Tribune, wrote to elected officials outlining what scanner access actually provides:
- Reporters can verify breaking news before official statements arrive, rather than waiting for a press release that may omit key details.
- When false information spreads on social media, scanner audio gives reporters something concrete to check it against.
- Dispatch traffic can establish whether shots were fired at officers before they returned fire—context that shapes public understanding of a use-of-force case.
- Real-time access captures the initial police response before it's shaped into an official account.
"This is one more way to shut off public access to what I would call kind of operational, raw data that can actually be quite revelatory as to whether a police department is doing its job properly."Jane Kirtley, Professor of Media Ethics and Law, University of Minnesota
When encryption failed: the Annunciation Church shooting
In February 2026, a mass shooting at Annunciation Catholic Church in Minneapolis tested the city's encryption policy under real emergency conditions.
As agencies from across the region responded to the active shooter situation, Minneapolis temporarily made police radio traffic publicly accessible again. The reason: encryption was blocking communication between agencies.
The contradiction
Minneapolis encrypted its radios citing safety and privacy. During the precise type of emergency that justifies those concerns, the city had to disable encryption to get agencies talking to each other.
Multi-agency responses at active shooter scenes depend on seamless communication. When departments use incompatible encryption, delays in coordination can cost lives.
The official justification vs. reality
What officials say
- Federal CJIS policy requires encryption for sensitive data
- Protects victim names, addresses, and personal information
- Officer safety concerns during active situations
- Rioters used scanners during 2020 protests
What critics point out
- CJIS requires encryption for specific data types, not blanket radio encryption
- Many departments protect privacy without full encryption
- Zero documented cases of scanner access harming officers
- Protesters using public information is exercising free speech, not a crime
Public Safety Commissioner Todd Barnette acknowledged there's "still a significant need for transparency around policing in the city." The department encrypted everything anyway.
The 911 dashboard: a transparency fig leaf
Minneapolis launched a public online dashboard as an alternative to scanner access. Here's what it offers:
| Feature | Open Scanner Access | Minneapolis Dashboard |
|---|---|---|
| Information delay | Real-time (seconds) | 30 minutes minimum |
| Audio context | Full officer communications | None |
| Incident details | Raw, unfiltered | Categorized, summarized |
| Breaking news value | Critical | Minimal |
| Independent verification | Possible | Impossible |
| Historical archive | Recorded by third parties | 12 hours, then limited archive |
Minneapolis officials acknowledged they lack the staffing or technology to provide delayed scanner streams like Chicago or Boston. The 30-minute dashboard is the only substitute on offer.
Twin Cities regional encryption
Minneapolis is part of a broader regional shift. The Twin Cities metro has been going dark one agency at a time:
Fully Encrypted
- Minneapolis Police (May 2025)
- Hennepin County Sheriff (2019)
- Ramsey County Sheriff
- St. Paul Police (Fall 2025)
- Washington County Sheriff
- Scott County Sheriff
- Edina, St. Louis Park, Plymouth Police
Partially Encrypted
- Dakota County Sheriff (tactical only)
- Some suburban departments
Planned Encryption
- Anoka (2028)
- Additional suburban agencies
The ARMER statewide system (Allied Radio Matrix for Emergency Response) makes encryption straightforward to enable, and Anoka's scheduled 2028 switch suggests this trend has more ground to cover.
The consent decree collapse
Four days before the five-year anniversary of George Floyd's murder, the Trump administration's Department of Justice withdrew from the federal consent decree.
The 169-page agreement had been unanimously approved by the City Council in January 2025. It required reforms addressing the DOJ's findings that MPD used excessive force, discriminated against Black and Native residents, and violated protesters' First Amendment rights.
Mayor Jacob Frey signed Executive Order 2025-01 committing to the consent decree's terms regardless, and the state human rights agreement remains active.
The federal withdrawal still removes outside enforcement. That leaves accountability to the same local institutions that failed to prevent the original abuses—now operating with less public visibility than before encryption.
Community oversight: backlog and frustration
Minneapolis created the Community Commission on Police Oversight (CCPO) to provide civilian review of police conduct. The commission has struggled. As of May 2024, 189 cases sat in queue. Commissioners reported inadequate training. Public access to case information was limited. The CCPO replaced an earlier body that was "marred by vacancies."
Minneapolis residents are now working with a civilian oversight body that can't keep up with its caseload and a department that no longer broadcasts its real-time activities.

Prepare to SpeakFrequently Asked Questions
When did Minneapolis police encrypt their radios?
Minneapolis Police Department completed full encryption of 911 radio dispatch on May 1, 2025. Testing began on April 14, 2025. The Hennepin County Sheriff's Office had encrypted in 2019, making it the first Minnesota agency to do so.
Why did Minneapolis encrypt police radios after George Floyd?
City officials cite federal CJIS data privacy requirements, though critics note the timing: encryption was implemented nearly five years after George Floyd's murder, when MPD was under intense accountability scrutiny and federal consent decree negotiations. The department initially released an inaccurate press statement after Floyd's death that was contradicted by witness video.
Is St. Paul police radio encrypted?
St. Paul police began encrypting in fall 2025, following Minneapolis. St. Paul officials justified the move by claiming protesters used scanner information during the 2020 unrest following George Floyd's murder. Both Twin Cities major departments are now encrypted.
What alternatives does Minneapolis offer for public information?
Minneapolis launched a 911 Emergency Incidents Dashboard that updates every 30 minutes with incident locations and types. However, this provides no real-time information, no audio context, and critics note the 30-minute delay makes it essentially useless for breaking news or emergency awareness.
Did Minneapolis reverse encryption during the Annunciation church shooting?
Yes. During the February 2026 mass shooting at Annunciation Catholic Church in Minneapolis, the city temporarily made police radio traffic publicly accessible to facilitate communication between multiple responding agencies. This highlights how encryption creates interoperability problems during major emergencies.
What is Operation Safety Net and how is it related to encryption?
Operation Safety Net was a sprawling surveillance program targeting civil rights activists and journalists after George Floyd's murder. An MIT Technology Review investigation revealed police used social media monitoring, cell phone tracking, and facial recognition against protesters. Critics argue encryption is part of a broader pattern of reducing police transparency in Minneapolis.
What is the status of the Minneapolis federal consent decree?
In January 2025, Minneapolis City Council unanimously approved a consent decree with the DOJ mandating police reforms. However, the Trump administration's DOJ withdrew from the agreement in May 2025. Minneapolis officials say they will implement all reforms regardless, and a separate state agreement with the Minnesota Department of Human Rights remains in effect.
