Mercy
The hotel management made an official statement, they said that they would not charge the girls with any crime if they came forward. Instead, they would give them a free lesson about Hawaiian art and culture so that they could learn to appreciate it more, and not ridicule it, but respect it.
This approach was the best possible solution. Sure, the young girls did something very silly and defaced a piece of work that didn’t belong to them, but that doesn’t mean they are hard-core criminals. They deserve mercy, but a chance to understand why what they did was wrong and how to be more respectful and understanding.
