I work with at risk individuals. I can understand no charges, because having a record can really mess a kid up employment wise now. But for the kids to get anything out of this other than either unresolvable guilt (not as likely nowadays) or the reinforced impression that they can act like savages and destroy other peoples property and livelyhood, they need to make retribution.
They should have to sit down with their parents, the beekeeper and the "mean man" who owns the land and work out community service. And then they should actually have to do the community service.
In our area, community service is figured at $10/hr, making $6000 worth 600 hours. One should be able to learn quite a bit about beekeeping, consequences of bad decisions, taking personal responsibility, and the value of work in that amount of time.
I know my parents would have required that we work for the beekeeper, the injured party, AND an equivalent 600 hours for the INTENDED victim.
We discussed this with our kids, and they agreed that if you tried to hurt someone and failed, the punishment should be the same as if you had been successful.
