Blue Alerts are issued when a law enforcement officer in the line of duty has been killed, seriously injured or is missing; or credible threats of serious injury have been made. Blue alerts can warn the public if a violent suspect is nearby, the type of vehicle (if any) they were last seen in and what civilians should do if they spot the suspect.
The Blue Alert network provides the means of quickly identifying, pursuing and capturing violent offenders who have hurt, killed or pose an imminent danger to law enforcement.
The Federal Communications Commission (FCC)added the Blue Alert to the nation's emergency alerting systems. With the creation of a dedicated Blue Alert event code in the Emergency Alert System, state and local law enforcement have the capability to push immediate warnings out to the public via broadcast, cable and satellite providers as well as to consumer smartphones through the Wireless Emergency Alert system.
