Confirmed Threat

Beginning in the early morning of Wednesday April 24, 2024, pro-Palestine protesters occupied Alumni Park at the center of the University of Southern California's University Park Campus. USC pushed a series of TrojansAlerts over the course of the day, beginning with notifications of 'significant activity at the center of the UPC campus' and escalating to warnings that anyone remaining in Alumni Park would be arrested; LAPD officers in riot gear arrested 93 people overnight. Within 24 hours, USC announced it would cancel its main-stage commencement ceremony, making it the first major U.S. university to do so over the encampment movement.

TrojansAlert is USC's emergency notification system for the University Park Campus and Health Sciences Campus, operated by USC's Department of Public Safety
The phrase 'significant activity' is a politically-neutral euphemism similar to Columbia's 'heightened activity', both spring 2024 alerts deliberately avoided characterizing the underlying protest

These past few weeks have been incredibly difficult for all of us. As your president, my responsibility is to uphold our Trojan values so that everyone who lives, learns, and works here can have safe places to live, learn, and speak. This week, Alumni Park became unsafe. No one wants to have people arrested on their campus. Ever. But, when long-standing safety policies are flagrantly violated, buildings vandalized, DPS directives repeatedly ignored, threatening language shouted, people assaulted, and access to critical academic buildings blocked, we must act immediately to protect our community. USC has long-standing protocols that allow for peaceful protesting, and we have been working successfully with our community to ensure these rules have been followed at gatherings, protests, and vigils taking place all year. USC also has firm rules regarding harassment and bullying that we will uphold.

A Message to the Trojan Community (We Are SC, signed President Carol L. Folt)we-are.usc.edufind archived copies
President Carol L. Folt published this message on USC's We Are SC official communications site on April 26, 2024, two days after the Alumni Park arrests and one day after USC announced the cancellation of its main commencement
The phrase 'This week, Alumni Park became unsafe' was the most-quoted line from the statement and reframed the encampment as a safety failure rather than a viewpoint dispute
Folt cited 'buildings vandalized, DPS directives repeatedly ignored, threatening language shouted, people assaulted, and access to critical academic buildings blocked' as the predicate for asking LAPD to clear Alumni Park
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.

There is significant activity at the center of the UPC campus due to a demonstration. There may be difficulty accessing that area. https://manager.everbridge.net/pub/1605082428743875

  • Sourceabsent1/25

    Final assessment

    Nearly all reads find no sender or authority named, only a generic Everbridge notification link; a lone dissent credited 'UPC campus' plus the Everbridge link as identifying the institution.

    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.

  • Hazardabsent2/25

    Final assessment

    Nearly all reads agree 'a demonstration' is not a specific named hazard type; two dissents credited naming the demonstration itself as sufficient.

    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

    Unanimous: 'the center of the UPC campus' clearly names the 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.

  • Guidanceabsent0/25

    Final assessment

    Unanimous: the message only notes possible difficulty accessing the area, which is informational rather than an explicit protective instruction.

    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.

  • Timeabsent0/25

    Final assessment

    Unanimous: no clock time or date is given.

    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

    Unanimous: no consequence or potential harm beyond the noted access difficulty is stated.

    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 April 24, 2024 USC Alumni Park occupation was one of the earliest large-scale pro-Palestine encampments at a private R1 university and is best remembered for the cascading institutional consequences it triggered. The occupation began in the early morning of Wednesday April 24 (organizers arrived at Alumni Park before dawn) when members of the USC Divest from Death Coalition erected tents and a stage at Alumni Park, the central plaza of the University Park Campus. USC's Department of Public Safety pushed multiple TrojansAlerts over the course of the day beginning with neutral 'significant activity' language and escalating to formal warnings of arrest. LAPD officers in riot gear arrived in the late afternoon, declared an unlawful assembly, and made 93 arrests overnight. The arrests came against an already-tense backdrop: USC had cancelled the commencement speech of class of 2024 valedictorian Asna Tabassum two weeks earlier on April 15, citing safety concerns about her pro-Palestine social media. Within 24 hours of the Alumni Park arrests, USC announced it would cancel the May 10 main-stage commencement ceremony, becoming the first major U.S. university to scrap graduation over the encampment movement; the school continued individual school-level ceremonies. USC closed the University Park Campus to non-affiliates and required Trojan ID cards for entry through limited gates. A second encampment was erected the next day; LAPD cleared it on May 5, 2024 with additional arrests. The case is significant for this archive because it documents an aggressive use of TrojansAlerts as an integrated component of a planned arrest operation, issuing escalating warnings hours before LAPD arrived to provide both community awareness and a contemporaneous legal record that participants had been notified of arrest risk.
Analysis

Key Findings

USC issued a sequence of escalating TrojansAlerts over roughly 9 hours, beginning with neutral 'significant activity' language and ending with arrest-imminent warnings, a graduated communication pattern designed both to inform and to establish legal notice
93 people were arrested overnight on April 24-25; one was charged with assault with a deadly weapon
USC became the first major U.S. university to cancel its main-stage commencement ceremony over the spring 2024 encampment movement, announcing the cancellation within 24 hours of the arrests
The Alumni Park arrests came two weeks after USC had cancelled valedictorian Asna Tabassum's commencement speech over similar safety concerns, compounding the institutional reputational impact
The 'significant activity' phrasing closely parallels Columbia's 'heightened activity', both private R1 universities used near-identical politically-neutral euphemisms in their alerts during the same week
Outcome
93 people arrested at Alumni Park overnight (April 24-25, 2024); one person arrested for assault with a deadly weapon. USC closed the University Park Campus to non-affiliates and cancelled the May 10 main-stage commencement ceremony. A second encampment was established the next day; LAPD cleared it on May 5, 2024. USC ultimately settled criminal charges against most arrestees through diversion programs.
