The program doesn't even guarantee that, the Dutch article has a sentence like "With Hack_Right, other punishments, such as imprisonment, are not excluded." There's a chance Google Translate got the sentence wrong but I doubt it.
In many countries a 12 years old is not eligible for prison. All minors do silly things. It is expected. If they tell to the child that can put him/her in prison they are lying and they parents must talk with a lawyer ASAP.
