How to Decrypt Police Radio: The Truth
Searching for ways to decrypt police radio? We'll give you the honest answer: you can't—and attempting to is a federal crime. But that frustration you're feeling points to a bigger problem worth understanding.
The Direct Answer
You cannot decrypt police radio. It's impossible.
Modern police encryption uses AES-256—the same encryption standard that protects military communications, bank transactions, and classified government data. No consumer product, no software, no hacking technique can break it.
This isn't about having the right equipment or technical skill. The encryption is mathematically unbreakable with current technology. There are more possible encryption keys than atoms in the observable universe.
It's Also a Federal Crime
Even attempting to decrypt police communications is illegal under the Electronic Communications Privacy Act:
- Up to 5 years in federal prison
- Fines up to $250,000
- Civil liability to the affected agency
This applies whether you succeed or not. The attempt itself is the crime.
Why Police Radio Can't Be Decrypted
Understanding why decryption is impossible helps explain why the "how to decrypt" question has no answer:
AES-256: Military-Grade Encryption
The Math
AES-256 has 2^256 possible keys. That's a number with 77 digits. For comparison, the observable universe contains approximately 10^80 atoms—a number with only 80 digits.
Brute Force?
If you could test one trillion keys per second, trying every possible combination would take approximately 3 × 10^51 years—billions of times longer than the age of the universe.
Quantum Computing?
Even theoretical quantum computers would only reduce AES-256 to AES-128 level security—still far beyond any practical attack. Usable quantum computers for this purpose remain science fiction.
Backdoors?
There are no known backdoors in AES-256. It's been extensively studied by cryptographers worldwide. If vulnerabilities existed, global financial systems would collapse.
How Police Encryption Works
Officer Speaks
Voice enters the radio microphone
Digitized
Voice converted to digital data
Encrypted
Radio hardware encrypts with AES-256 key
Transmitted
Scrambled signal broadcast
Blocked
You hear digital noise or silence
Only radios programmed with the matching decryption key can decode the audio. Police departments strictly control these keys.
Why Are People Searching for This?
If you're reading this article, you've discovered that your access to public safety information has been cut off. You're not alone—and your frustration is valid.
The Encryption Explosion
Police operated with open radio communications for 70+ years. Suddenly, after 2020, encryption surged nationwide. What changed?
Before 2020
- Most departments unencrypted
- Scanners widely used by public, media, emergency workers
- Real-time transparency was the norm
The Trigger
During 2020 protests, open scanners documented:
- Racist remarks by officers
- Coordination of aggressive tactics
- Discrepancies between official statements and actual communications
After 2020
- Rapid encryption adoption
- Major cities like Chicago, NYC, Denver went dark
- $390M+ spent on encryption systems
The Pattern
Encryption became "essential" exactly when scanners started exposing misconduct. The timing suggests this is about controlling information, not protecting safety.
What the Police Claim vs. What the Evidence Shows
"Officer Safety"
Criminals use scanners to ambush officers or evade capture.
Evidence:
Zero documented cases of scanner-related officer harm in decades of open communications. When Palo Alto requested evidence, their search returned no results. The claim is theoretical, not factual.
Read the full analysis →"Victim Privacy"
Sensitive victim information goes over the radio and must be protected.
Evidence:
Better solutions exist that don't require blanket encryption. Mobile data terminals can send sensitive info via text. Training can prevent officers from broadcasting sensitive details. Hybrid systems encrypt only what's necessary.
Read the full analysis →"Technology Upgrade"
Encryption is just part of modern radio system upgrades.
Evidence:
Encryption is optional on modern P25 systems. Many departments use digital P25 without encryption. The technology supports both—encryption is a policy choice, not a technical requirement.
Learn about encryption types →"Operational Security"
Investigations are compromised when the public can listen.
Evidence:
Tactical channels were always available for sensitive operations. Undercover officers, SWAT teams, and narcotics units have used encrypted tactical channels for decades—without encrypting routine dispatch.

You can't decrypt police radio. But you have other options:
What We Lose When Police Encrypt
Your inability to decrypt police radio isn't just a personal inconvenience—it represents a fundamental shift in the relationship between police and the public.
Real-Time Emergency Information
During active shooters, wildfires, or severe weather, scanner access provides life-saving information before official channels can respond. The Highland Park shooting demonstrated this—families used scanner feeds to locate loved ones and take shelter.
Independent Journalism
Reporters can no longer verify police claims or provide real-time breaking news coverage. The public is entirely dependent on official statements. RTDNA ranks encryption as the #1 threat to journalism.
Democratic Accountability
Scanner access was the only truly independent, real-time oversight of police activities. With encryption, misconduct happens without witnesses. The Uvalde scanner traffic revealed the truth about delayed response—information officials initially hid.
Community Trust
Transparency builds trust; secrecy erodes it. When police operate in the dark, communities become more suspicious, not less. Encryption sends the message: "You can't be trusted with information about your own safety."
Two Cities, Two Outcomes
Highland Park, IL (2022)
Unencrypted
During a mass shooting at a July 4th parade, scanner listeners heard real-time alerts. Families sheltered in place, located loved ones, and spread warnings. Open scanners saved lives.

Encrypted
After Chicago encrypted, the public lost all real-time awareness. During emergencies, residents depend on delayed official statements. Journalists can't verify police claims.
Read about Chicago →Better Alternatives Exist
Legitimate privacy and security concerns don't require eliminating all public access. Proven alternatives include:
Hybrid Systems
Keep 85-90% of routine dispatch open while encrypting tactical channels for SWAT, undercover, and sensitive operations. This is the "gold standard" used by many transparent departments.
Mobile Data Terminals
Send sensitive information (victim names, SSNs, addresses) via text to in-car computers instead of broadcasting over voice radio.
Selective Encryption
Encrypt specific talkgroups for narcotics, gang units, and undercover operations while keeping general dispatch open to the public.
Officer Training
Train officers on proper radio protocol to prevent broadcasting sensitive information in the first place. Most routine calls don't require secrecy.
Take Action: Fight the Policy, Not the Technology
You can't hack your way past encryption. But you can fight to change the policy. Communities have successfully stopped and even reversed encryption decisions through organized advocacy.
What You Can Do
- Contact your city council — Encryption decisions are often made without public input. Demand transparency and evidence of need.
- Request public records — File FOIA requests for evidence of scanner-related harm. There usually isn't any. Our ready-to-use templates make this easy.
- Attend police commission meetings — Public comment periods let you put concerns on the record. Use our testimony scripts.
- Contact local journalists — Media coverage brings public attention. Reporters are natural allies—encryption hurts them too.
- Build a coalition — Fire departments, disability advocates, and civil liberties groups share your concerns. Learn how to recruit allies.
