Indianapolis Police Scanner: Racing City Holds the Line on Transparency
Home to the Indianapolis 500 and 350,000-person events, Indianapolis remains one of the largest U.S. cities where police scanner access is still available. But surrounding counties are going dark—and the pressure is mounting. Here's what you can still hear and how to protect what remains.
Indianapolis area at a glance
IMPD is studying encryption but hasn't implemented it, keeping the nation's 17th largest city accessible to scanner listeners. At any given time, more than 800 people listen to the Indianapolis police channel on Broadcastify.
Indiana State Police has also chosen to remain "in the clear" on the SAFE-T system. Surrounding counties are another story: Hamilton County encrypted without public input in 2023, and Hendricks County went dark in 2022. The pressure on Indianapolis to follow has grown since.
Why Indianapolis scanner access matters: major events
Indianapolis 500
350,000 spectators
The world's largest single-day sporting event draws nearly 350,000 people to Indianapolis Motor Speedway. Open scanner access lets media, families, and emergency personnel track incidents in real time. The 2024 race sold out for the first time since 2016.
NFL Colts at Lucas Oil Stadium
67,000+ capacity
IMPD traffic control for Colts games uses the Indianapolis-Marion County P25 TRS. Open scanner access helps fans and media track incidents, accidents, and security responses around the stadium.
NBA Pacers at Gainbridge Fieldhouse
Downtown core events
With Gainbridge Fieldhouse in the heart of downtown Indianapolis, scanner access provides real-time awareness for commuters, businesses, and residents during high-traffic events.
When 350,000 people gather for the Indy 500, real-time scanner access helps journalists verify what's happening on the ground, lets families track incidents near the speedway, and gives the public a source of information that isn't filtered through official channels. Encrypting that feed during one of America's largest public gatherings creates an information gap with real consequences.

The Senate Bill 117 problem: law misused for full encryption
What the law actually says
Indiana Senate Enrolled Act 117 (2022) prohibits law enforcement from transmitting social security numbers over non-encrypted radio. The law provides privacy protections for specific sensitive information.
How counties are misusing it
Hamilton and Hendricks counties cited SB 117 as justification for encrypting all police communications—far beyond the law's intent. State Senator Kyle Walker, the law's author, stated that full encryption was never the intent of the legislation.
"The ability of law enforcement to use non-encrypted radios for any other means they deem appropriate is unchanged."— State Senator Kyle Walker, SB 117 sponsor
Hamilton County: encryption without public input
What Happened
Hamilton County, IN - August 1, 2023
- All police radio transmissions encrypted
- No public hearing or community input
- Decision made by communications center, not elected officials
- Cited SB 117 despite law's limited scope
- Created 5-minute delayed website as the only public alternative
What Indianapolis could do
Marion County, IN - Still deciding
- Hold public hearings before any encryption decision
- Require city council oversight, not just departmental approval
- Consider a hybrid model: tactical channels encrypted, dispatch open
- Maintain real-time journalist access to breaking calls
- Preserve public monitoring during high-attendance events
Hamilton County now provides a website with call information on a 5-minute delay. However, FOX59 found that on some calls—including "shots fired"—the address field was blank. Delayed, incomplete information is no substitute for real-time scanner access.
Why transparency matters now: IMPD under scrutiny
2023 saw the highest number of IMPD officer-involved shootings in nearly a decade—up from just 4 in 2022. At least 12 people were killed by police in Marion County that year, compared to 3 in 2022.
The U.S. Department of Justice announced a review of IMPD's officer-involved shootings through its Community Oriented Policing Services (COPS) office. IMPD Chief Christopher Bailey requested the review himself.
With that review underway, restricting radio access to real-time police activity would move Marion County in exactly the wrong direction. Scanner access gives journalists, advocates, and residents information that official after-action reports can take days or weeks to provide.
Community Leaders Speak Out
"I think it would heighten tension and distrust."— Rev. Charles Harrison, responding to potential encryption, leads community response to crime scenes
"Trust is earned, it's not given, and the community deserves to know what's happening in their neighborhoods."— IMPD Chief Chris Bailey, announcing transparency portal
How to listen to Indianapolis area agencies

Protect Indianapolis scanner access
Indianapolis is still accessible, but IMPD is actively studying encryption and surrounding counties have already gone dark. That combination tends to move in one direction over time.
Contact Your City Councilor
Indianapolis City-County Council has oversight over IMPD policies. Thank them for maintaining transparency and urge them to protect scanner access if encryption is proposed.
Thank Chief Bailey
Chief Chris Bailey requested the DOJ review and launched a transparency portal. Recognize these steps and encourage continued commitment to openness.
Point to Major Events
The Indy 500 brings 350,000 people to Indianapolis. Ask officials: what happens during an emergency at a major event when no one can hear police communications?
Challenge County Encryption
If you're in Hamilton or Hendricks counties, push back. The SB 117 justification doesn't hold up—the law's author says full encryption was never the intent.

Yes. In November 2025, IMPD launched impdtransparency.indy.gov with searchable maps for incident reports, calls for service, and traffic data. Police Chief Chris Bailey stated 'Trust is earned, it's not given, and the community deserves to know what's happening in their neighborhoods.' However, this is not a substitute for real-time scanner access.
