What This Means
This agency encrypts tactical channels used for special operations, SWAT, and sensitive investigations. Regular dispatch may still be accessible.

- 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
Take Action
