What This Means
This agency encrypts all of their radio communications, including routine dispatch. The public, journalists, and even other first responders cannot monitor their activities.
Impact on Transparency
- Journalists cannot monitor police activity for breaking news or investigative reporting
- Community members cannot track police response to incidents in their neighborhood
- Researchers cannot study police communication patterns and response times
- Other first responders may face interoperability challenges during emergencies
