Finally, the police get tired of dealing with him, and decide to lock him in a cell to teach him a lesson. His mother decides to do something about it. As they leave, however, a crowd forms. They stare at the mother, giggling and whispering behind their hands. One man even takes a photograph.
Forgiveness is never cheap.
The mother had a choice. She could have said, Well, he did a stupid thing, he needs to pay for it, it'll teach him a lesson all the sorts of things we say when we're concerned for justice.

In the same way, we have done wrong.
