While the arrest seems like overkill, in defense of the receptionist reporting the message to police in the first place, this was not a ring tone of the actual Fresh Prince theme with music. It was just the student himself speaking the lyric “And all shooting some b-ball outside of the school” as a voice mail message. Not to pass snap judgments on a 19-year-old who's still in high school, but perhaps he's not the most articulate person, and I can easily see how "b-ball" and "people" could get mixed up in a poor sounding recording, especially when it's just spoken without musical accompaniment, which would make you question its seriousness. Plus, leaving a message with your intentions to shoot up a school or workplace is not unheard of for mass shooters. So, I don't blame her for taking precautions, especially in this day and age.
Yeah, but why get all the facts and think things through when you can just blast schools for fun?
