(b) Individual circumstances requiring a search may include incidents on school property, including school buses, involving, but not limited to, the use of dangerous weapons, drugs or drug paraphernalia by students that are known to the principal or other staff members, information received from law enforcement, juvenile or other authorities indicating a pattern of drug dealing or drug use by students of that school, any assault or attempted assault on school property with dangerous weapons or any other actions or incidents known by the principal that give rise to reasonable suspicion that dangerous weapons, drugs or drug paraphernalia are held on school property by one (1) or more students.
