Confirmed Threat

On May 21, 2024, University of Michigan police cleared the pro-Palestinian encampment on the Diag at approximately 6:00 a.m. EDT after a month-long occupation. The clearing was prompted by a fire marshal inspection that determined a catastrophic loss of life was likely if a fire occurred. Four people were arrested.

Ensuring that the campus is safe – for students, faculty, employees, university visitors, and protestors – is a paramount concern, which is why the university has provided 24-hour security for the encampment over the past four weeks. Following a May 17 inspection by the university fire marshal, who determined that were a fire to occur, a catastrophic loss of life was likely, the fire marshal and Student Life leaders asked camp occupants to remove external camp barriers, refrain from overloading power sources, and stop using open flames. The protesters refused to comply with these requests. That forced the university to take action and this morning, we removed the encampment. The disregard for safety directives was only the latest in a series of troubling events centered on an encampment that has always violated the rules that govern the Diag – especially the rules that ensure the space is available to everyone. In late April and early May, individuals in the encampment replaced Diag bricks with concrete and painted over the Block M on the center of Diag. Spray paint graffiti was found on walkways, on the Michigan Union sign and on the fountain outside the League. These actions were not free speech; they were destruction of property. A protest outside the University of Michigan Museum of Art descended into violence on May 3. Participants in the encampment helped organize the protest and issued calls on social media for others to join them.

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.

    Final assessment

    A strong majority credits references to 'the university,' the fire marshal, and Student Life leaders as identifying the issuing authority, with a few early reads dissenting that no named sender appears.

    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.

  • Hazardpresent22/25

    Final assessment

    A strong majority finds fire risk explicitly named via the fire marshal's finding that 'a catastrophic loss of life was likely' if a fire occurred, with a few dissents calling it only past narrative.

    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.

    See all 25 individual reads

  • Locationpresent25/25

    Final assessment

    Unanimous agreement that 'the Diag' is named as the specific location.

    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

    Unanimous agreement that the message describes past actions taken by the university but gives no protective instruction to current recipients.

    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

    Unanimous agreement that the message gives specific timing via 'this morning' and the 'May 17 inspection' reference.

    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.

  • Impactpresent25/25

    Final assessment

    Unanimous agreement that 'a catastrophic loss of life was likely' explicitly conveys severe potential harm.

    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

The clearing of the University of Michigan encampment on May 21, 2024 came after a month of occupation on the Central Campus Diag. Protesters had established the encampment in late April, demanding the university divest from companies connected to Israel. The situation escalated on May 3 when a protest outside the University of Michigan Museum of Art turned violent, and on May 15 when protesters staged demonstrations at the private residences of Board of Regents members. The immediate trigger for the clearing was a May 17 fire marshal inspection that found catastrophic fire safety hazards: densely packed tents with no egress paths, highly combustible materials, overloaded power sources, open flames, and a vandalized fire hydrant that was no longer serviceable. After camp occupants did not comply with the safety requests, according to the university's account, it ordered the clearing. Michigan Attorney General Dana Nessel later charged 11 people in connection with the protest incidents.
Outcome
Four people were arrested after officers issued three verbal warnings over 15 minutes. The encampment had been in place since late April. The fire marshal had found vandalized fire hydrants, blocked egress paths, and overloaded power sources. Eleven people were later charged by the Michigan Attorney General.
