The new alert was proposed by FCC Chairman Ajit Pai in May and a Notice of Proposed Rulemaking (NPRM) was released for the Commission to consider at today's meeting. In a press release, the FCC said, "Blue Alerts can be used to warn the public when there is actionable information related to a law enforcement officer who is missing, seriously injured or killed in the line of duty, or when there is an imminent credible threat to an officer. As a result, a Blue Alert could quickly warn you if a violent suspect may be in your community, along with providing instructions on what to do if you spot the suspect and how to stay safe."
There are 27 states that already have their own version of the Blue Alert, but the FCC's proposal is intended to provide a national system that states can adopt. The new alert is similar to the Amber Alert that has had a fair amount of success since its creation in 1996. According to the Department of Justice, 868 children have been rescued because of the alert.
The press release says the NPRM invites the public to comment on the proposal. While the final NPRM hasn't been released by the FCC yet, once it has been, you can tell them what you think here.
