Police Encryption in Michigan
A tale of two cities: Detroit went fully encrypted in 2020, cutting off public access to police communications in a city with a complex history of police-community relations. Meanwhile, Grand Rapids—Michigan's second largest city—maintains open scanners, demonstrating that transparency and public safety can coexist.
Michigan at a Glance
Michigan's police encryption story is defined by contrast. The Detroit metropolitan area—home to over 4 million people—has largely gone dark, with Detroit PD, Wayne County Sheriff, and Michigan State Police all fully encrypted. Yet just 150 miles west, Grand Rapids and surrounding Kent County maintain open communications.
This divide isn't just geographic—it reflects different philosophies about policing and transparency. Detroit, with its troubled history of police misconduct and the legacy of the 1967 uprising, chose encryption. Grand Rapids, facing similar challenges but taking a different path, proves that large cities can remain transparent.
Detroit: Going Dark in 2020
The Decision
In 2020, amid national protests following George Floyd's murder, Detroit Police Department completed its transition to full encryption. The timing was significant—just as public demands for police accountability reached a peak, Detroit made it harder for the public to monitor police activity.
DPD leadership cited officer safety and operational security as primary reasons. Critics noted that Detroit had operated with open scanners for decades without documented incidents of scanner-related officer harm.
Historical Context
Detroit's relationship with police accountability is fraught. The 1967 Detroit Rebellion was sparked by police conduct. For decades, Detroiters used scanners to monitor police activity in their neighborhoods—a form of community oversight in a city where trust in police has been hard-won.
The Department of Justice investigated Detroit PD in the early 2000s, resulting in federal oversight. Some argued that encryption undermines the transparency gains made during that reform period.
Impact on Detroit
Since encryption, Detroit journalists report significant challenges covering breaking news. The Detroit Free Press and Detroit News, which long relied on scanners for police reporting, now depend on delayed official notifications and tips.
Community organizations that monitored police activity in neighborhoods with high crime or frequent police encounters have lost a key tool for oversight. The ability to document police response times and behaviors has been curtailed.
Grand Rapids: The Transparency Model
Why Grand Rapids Stayed Open
Michigan's second largest city has faced calls to encrypt but has maintained open communications. Grand Rapids PD leadership has stated that transparency serves both community trust and officer safety—the public knowing what police are doing creates accountability that benefits everyone.
Kent County Sheriff's Office similarly maintains open communications, covering a population of over 650,000 with no documented incidents of scanner-related officer harm.

Regional Analysis
Metro Detroit
The tri-county area of Wayne, Oakland, and Macomb counties has largely gone encrypted. Detroit PD and Wayne County Sheriff are fully dark, while Oakland and Macomb counties have mixed status with ongoing transitions toward encryption.
- Detroit PD: Fully encrypted since 2020
- Wayne County: Fully encrypted
- Oakland County: Partial/transitioning
- Macomb County: Mixed by department
West Michigan
Grand Rapids and the surrounding region stand in stark contrast to Detroit. The area's commitment to transparency extends beyond the city itself to Kent County and neighboring jurisdictions.
- Grand Rapids PD: Open
- Kent County Sheriff: Open
- Suburban departments: Generally open
- Kalamazoo: Partial encryption
Central Michigan
The Lansing area and mid-Michigan have taken varied approaches. Lansing PD has partial encryption while many surrounding communities remain open. Flint has implemented partial encryption amid ongoing recovery from the water crisis.
- Lansing PD: Partial encryption
- Flint PD: Partial encryption
- East Lansing: Partial (MSU campus)
- Rural areas: Generally open
Northern Michigan
Michigan's northern regions, with smaller populations and tight-knit communities, have largely maintained open communications. Tourism-heavy areas value the public information aspect of scanner access.
- Traverse City: Mostly open
- County sheriffs: Generally open
- Resort communities: Open
- Upper Peninsula: Mostly open
Michigan Encryption Timeline
Michigan State Police Encrypts
MSP completes statewide encryption. Coverage of highway incidents and state-level law enforcement becomes dependent on official notifications rather than real-time scanner access.
Detroit Goes Fully Encrypted
Amid national protests for police accountability, Detroit PD completes full encryption. The largest Michigan city goes dark, ending decades of public scanner access.
Metro Detroit Counties Follow
Wayne County Sheriff encrypts fully. Oakland County and suburban departments begin transitions. Ann Arbor and Lansing implement partial encryption.
Flint Implements Partial Encryption
Flint, still recovering from the water crisis, implements partial encryption. Sterling Heights and other Macomb County departments follow the encryption trend.
Grand Rapids Stands Firm
Despite pressure and the example of Detroit, Grand Rapids maintains commitment to open communications. The city serves as proof that transparency remains viable for large Michigan cities.
Impact on Michigan Communities
Detroit Media
The Detroit Free Press, Detroit News, and local TV stations have fundamentally changed their breaking news operations. Stories that once broke via scanner monitoring now arrive through delayed official channels or tips—often hours after events occur.
Community Oversight
Detroit's history of police-community tensions makes oversight particularly important. Organizations that monitored police activity to document response patterns and conduct have lost a crucial tool. This matters in neighborhoods where trust in police remains fragile.
The Grand Rapids Model
Grand Rapids demonstrates that Michigan's second-largest city can operate effectively with open scanners. Local media, community organizations, and residents benefit from real-time access without documented negative impacts on officer safety.
Auto Industry Angle
Michigan's auto manufacturing heritage means large industrial facilities and transport corridors. Scanner access has historically helped communities monitor incidents affecting major employers and traffic patterns—now limited in metro Detroit.
What Michiganders Can Do
Celebrate Grand Rapids
Grand Rapids and Kent County prove that transparency works. Publicly recognize their commitment to open communications. When advocates elsewhere argue encryption is inevitable, point to Michigan's second-largest city as proof otherwise.
Engage Local Government
Many Michigan cities are still evaluating encryption. Attend city council meetings when radio system contracts are discussed. Share the Grand Rapids model as an alternative to following Detroit's path.
Support State Legislation
Michigan's legislature could establish statewide transparency standards. Contact your state representative and senator to support legislation requiring public access provisions—or at minimum, requiring public hearings before encryption decisions.
Document Impact
If you're in an encrypted area and encryption has affected your access to public safety information, document it. These stories build the case for transparency—whether you're a journalist, community organizer, or concerned resident.
