On the one hand, you would hope the school would know better, and that a rifle locked up out of sight in a vehicle is not the next Columbine.
On the other, you would hope the student would have the sense to realize that schools are insane, and of course they don't know better.
The excuse that they were going to be "working on them" sounds lame. Are they amateur gunsmiths? The people at the school know what kind of reputation these young lads have and if there is nothing to it, then I'd hope they would be able to return to school. Somehow, another student learned that the guns were there. How? We haven't heard the rest of the story.
