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

Take Action

Fight encryption at St. Charles County Police. Contact local officials to demand transparency.
