About Missouri Blue Alert


In 2015, Congress passed the Rafael Ramos and Wenjian Liu National Blue Alert Act, named in honor of two New York City police officers killed in an ambush attack on December 20, 2014. The Act establishes a voluntary nationwide system to give police an early warning of threats against police officers and to aid in the apprehension of suspects who have killed or seriously injured an officer. In 2016, the COPS Office was asked to implement the Blue Alert Act and establish a National Blue Alert Network.

Reason for Blue Alerts

Blue Alerts provide for rapid dissemination of information to law enforcement agencies, media, and the public about violent offenders who have killed, seriously injured, or pose an imminent and credible threat to law enforcement. Blue Alerts can be transmitted via wireless devices and through the Emergency Alert System (EAS). The National Blue Alert Network works to encourage, enhance, and integrate Blue Alert plans throughout the United States.
