As a continued precaution, please stay clear of the building and immediate area. 10:20 p.m. The Recreation Center is still being searched by emergency personnel and an explosive K9 Team. There is still nothing to indicate there is an explosive device in the building. As a precaution, please stay clear of the building and immediate surrounding area. 10:10 p.m. At this point, there is nothing to indicate that there is an actual device or credible threat. However, all precautions are being taken and the building is still being searched. 9:55 p.m. MUPD has received an anonymous report of a bomb threat to the Mizzou Recreation Center. As a precaution, the building has been evacuated and MUPD officers and an explosive K9 team will be checking the building.

Message elements

How the first alert is built

To check this alert, Claude Opus 5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Final assessment

    Present, 25 of 25. "MUPD has received an anonymous report" and the deployment of "MUPD officers and an explosive K9 team" mark the responding agency.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    Present, 25 of 25. The threat is specified as "a bomb threat to the Mizzou Recreation Center", with searches for an "explosive device".

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationpresent25/25

    Final assessment

    Present, 25 of 25. Everything centers on "the Mizzou Recreation Center" and, in the guidance, "the area of the Recreation Center and immediately surrounding areas".

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    Present, 25 of 25. The building "has been evacuated" and readers are repeatedly told, "please stay clear of the building and immediate area".

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

    Present, 25 of 25. Six updates are stamped from "9:55 p.m." to "11:59 p.m." under the June 23, 2017 header.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactabsent0/25

    Final assessment

    Absent, 0 of 25. Consequences are never described; the messages instead stress "there is nothing to indicate that there is an actual device or credible threat".

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
