Law enforcement agencies across St. Clair County are finalizing a transition to encrypted radio communications this week in a move that will effectively end the public’s ability to monitor police activity via traditional scanners and mobile apps.
The transition, which is expected to be fully implemented by Wednesday, is part of a broader effort to comply with state-mandated safety protocols. Local officials point to the increasing frequency of tactical information being shared on social media in real-time as a primary driver for the change. They say specifically, the broadcasting of movements involving Special Response Teams and other specialized units create significant safety concerns for both officers and the public during active scenes.
While the encryption will silence police frequencies for the general public, it does not immediately apply to all emergency services. Fire department and EMS radio traffic are slated to remain on open channels for the time being, with their transition to encrypted systems not expected until sometime next year.
The shift follows a growing trend among Michigan law enforcement agencies seeking to protect sensitive personal data and tactical strategies from unauthorized monitoring. Public information regarding major incidents will continue to be shared through official press releases and department social media updates.
