Michigan’s alert system for public threats - such as mass shootings and terrorist attacks - is up and running. Governor Rick Snyder signed the bill to create the alerts into law in June. The system was set up in response to the February shooting spree by an Uber driver in Kalamazoo.
It sends notifications through TV, radio, and text alerts - much like AMBER Alerts that notify people about missing children. Michigan State Police define a public threat as a “clear, present, persistent, ongoing and random threat to public safety.”
