MTSU alert quoted verbatim by Newsweekx.comfind archived copies
Sent shortly after MTSU Police responded to shots fired at the Murphy Center area around 8:51 PM CDT on May 18, 2022
The two-option construction ('Leave the area if possible or shelter in place') is more permissive than typical active-threat alerts that mandate sheltering, reflecting that the shooting was in an outdoor area near the tennis courts where many graduation attendees were already exiting
The alert names 'Murphy Center' specifically, which was hosting the Riverdale High School graduation under a Rutherford County Schools rental, not an MTSU event

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.

MTSU ALERT: Shooting reported at Murphy Center. Leave the area if possible or shelter in place. Report suspicious activity to MTSU Police: 615-898-2424.

    Final assessment

    Present, unanimously: the branded MTSU ALERT tag opens the message and MTSU Police are named.

    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, unanimously: a reported shooting is named directly.

    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, unanimously: Murphy Center is named as the site of the reported shooting.

    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, unanimously: recipients are told to leave the area if possible or shelter in place, and given a number for reporting.

    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.

    Absent, unanimously: no time, date or duration is given for the reported shooting.

    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, unanimously: no consequence or severity of the shooting is described.

    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.

About this analysis
Context

Background

On the evening of May 18, 2022, officers responded to the MTSU campus after reports of a shooting near the tennis courts adjacent to Murphy Center at approximately 8:51 PM CDT. The shooting occurred following Riverdale High School's graduation ceremony, which was held inside the Murphy Athletic Center as part of Rutherford County Schools' annual arrangement to rent the university's facilities for high school commencements. Two people were found with gunshot wounds. Hasani Brewer, 18, was identified as the victim who was killed, and a second person was hospitalized in critical condition. A 17-year-old was taken into custody and charged in connection with the shooting. Investigators determined that the suspect and the victims knew each other and had all attended Riverdale High School; an argument at the graduation escalated and spilled over to the tennis courts where the suspect drew a weapon. MTSU noted that Murphy Center was rented by the county school system for commencement and that the shooting was not related to any university event.
