On June 8, 2022, Broward College's Central Campus in Davie, Florida, was locked down and ultimately closed for the day after a false report of an active shooter. Davie Police searched Building 9 where the shooting was reported and found no activity, no victims, and no injuries. The hoax was part of a cluster of false active-shooter calls that day affecting several Davie schools, and the college issued an all-clear once the buildings were cleared.

INITIAL ALERTTwitter/X
Verified verbatimInsider Paper, quoting Broward College's alert tweet113 chars
There is police activity at Central Campus near building 9. Please avoid the area until further notice. Message 1
The trailing 'Message 1' tag marks this as the first message in the alert sequence, a numbering convention carried over from the mass-notification system that mirrored the alert to the college's Twitter account.
The message says only 'police activity' and never mentions a shooter, even though the triggering call was a false active-shooter report; police were still searching Building 9 when it went out.
Davie Police later said they received several calls about active shooters at multiple area schools that day, all of which were false.

All clear. Police have cleared all potential threats on Central Campus. Normal activity will resume tomorrow. Message 3.
This sentence tracks how NBC 6 and CBS Miami described the college's all-clear, but it is unclear whether the outlets were quoting the post or paraphrasing it, so the message stays unconfirmed; Central Campus remained closed for the rest of the day.
Reporting confirmed there were no victims or injuries and that detectives were investigating the origin of the false call.
Message elements

How the first alert is built

To check this alert, Claude (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.

  • Sourceabsent0/25

    Final assessment

    All 25 reads agree the element is absent: no sender, agency, or branded signature identifies who issued the message.

    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.

  • Hazardabsent0/25

    Final assessment

    All 25 reads agree the element is absent: it cites police activity but names no specific hazard.

    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.

    Final assessment

    All 25 reads agree the element is present: it names Central Campus near building 9.

    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.

    Final assessment

    All 25 reads agree the element is present: it instructs recipients to avoid the area until further notice.

    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.

  • Timepresent25/25

    Final assessment

    All 25 reads agree the element is present: the phrase until further notice conveys a recency timeframe.

    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 by unanimous agreement; all reads note it merely reports police activity and to avoid the area with no stated harm or danger.

    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

Broward College serves roughly 46,000 students across Broward County, with its Central Campus in Davie. On June 8, 2022, a false report of an active shooter triggered a lockdown and a large police response there. Local 10 reported that officers searched Building 9 (where the shooting was supposedly occurring) and found no activity. NBC 6 noted the same morning brought false active-shooter calls to several other Davie schools, including Nova High School and McFatter Technical College, marking it as a coordinated swatting event. CBS Miami reported the college closed Central Campus for the rest of the day and gave an all-clear once buildings were searched. No one was hurt, and detectives investigated the origin of the call.
