Encryption Makes Communications More Secure
This claim is not supported by evidence.
The Claim
Encrypted digital radio systems are more reliable, secure, and effective than traditional open radio communications.
The Evidence
Encryption creates new problems and failures.
- Interoperability issues: Different agencies' encrypted systems often can't communicate with each other during multi-agency responses
- Technical failures: Documented cases of garbled transmissions, including an officer calling 'I'm hit' but the message was unintelligible due to encryption issues
- Complexity costs: Encrypted systems require expensive infrastructure, ongoing maintenance, and regular key distribution
- Training challenges: Officers must manage encrypted vs. open channels, creating confusion during high-stress situations
The Reality
Encryption adds technical complexity that can reduce communication reliability rather than improve it:
- When police encrypt but fire and EMS departments don't, coordination during joint responses gets complicated
- During major incidents requiring mutual aid from neighboring departments, incompatible encrypted systems create barriers that don't exist with open radio
- Encryption keys can fail to load, radios lose sync, and systems go down — leaving officers unable to communicate during exactly the moments it matters most
- Departments spend millions on encryption infrastructure that provides no documented safety benefit while creating real operational problems
Bottom Line
When police departments make this claim, ask them for evidence. The documented facts don't support it.
