  "context": "The [John B. Cade Library](https://en.wikipedia.org/wiki/Southern_University_and_A%26M_College) is the main research library on [Southern University's Baton Rouge campus](https://en.wikipedia.org/wiki/Southern_University_and_A%26M_College). When a potential threat was reported just before noon on September 30, 2025, the university moved quickly to evacuate the building and coordinate with multiple law enforcement agencies. Witnesses observed [Baton Rouge Police, East Baton Rouge Parish Sheriff's deputies, and ATF agents closing streets around the library](https://www.theadvocate.com/baton_rouge/news/crime_police/southern-university-threat/article_c21733df-053e-47e7-a83a-8ec5d3fc80f7.html), an unusually heavy multi-agency response that reflected the heightened security posture following repeated threats to Southern's campus that month. This was the third major safety incident at the university in September 2025: [the September 11 HBCU-wide hoax threats](https://www.wwno.org/education/2025-09-11/southern-university-other-hbcus-close-due-to-potential-threat) that prompted a multi-day campus closure, the [September 22 Fisher Hall suspicious-item evacuation](https://www.wafb.com/2025/09/22/southern-university-evacuates-students-fisher-hall-no-threat-campus/), and now the Cade Library evacuation. No credible threat was ultimately found in any of the three incidents, but the cumulative disruption to academic operations at one of Louisiana's largest HBCUs was significant.",
