A kid in high school is upset that he's short on credits to graduate and tells his friend, in a private conversation, that he's going to "blow up the school, shoot it" and that he knew how to get an Army grenade. The friend thinks that the kid is joking, but isn't certain.
The Court of Appeal holds that's a felony, and counts as "a false report [that] a bomb or other
explosive device would be placed in [the] school."
