If a child runs into a store and steals candy, would you reward them with more candy?

I read today that a 15 year-old romanian boy was arrested for the third time for hijacking a bus. The boy wants to be a bus-driver more than anything else, the authorities realize that sending this 15 year old boy to prison would probably ruin his life so instead the bus station officials have agreed to begin training him to become a bus driver- now why can't we all be like that?
