I could use some help with this

rule 4 states- A Major Disciplinary Infraction for Possession of a Weapon in school is a violation that occurs in school and severely interferes with the learning and safety of others, and is of a threatening or harmful nature.

Just before high school started, students Sally and Nick were in a heated argument in the schoolyard when Sally flashed what appeared to be a gun to Nick and said, "You better stay away from me." This was witnessed by several students, one of whom squealed on Sally, who was later found with an airsoft gun in her purse.

Break the rule down to its elements. Present a comprehensive phrasing of the issue/s involved. Applying the rule to the facts provided, analyze the rule as to the given hypothetical. Conclusion: Did Sally Violate Rule 4?
