My assistants are looking into this and will respond when they receive an answer.
Update 10/25/19 from BCPD: “When a crime on or near the campus is reported, BCPD promptly assesses the potential danger or threat it presents to the campus community or a portion thereof in an effort to determine whether or not an immediate threat exists, which would result in a timely notification. Many times, incidents are isolated to specific areas, and a community awareness bulletin is issued and disseminated to the affected area.”
