The danger in jumping to a conclusion with these media storied is that the media often spin it in a way that provokes outrage or emotion because that generates interest and thus sells copies. They often omit the context so the story appears ludicrous and irrational. While I'm in no way justifying the decision if it is indeed as simple as the story makes it seem, I'm just saying you should keep an open mind that there are other possibilities, considering the only insight we have is from the boy's defence lawyer and do not hear the police's justifications or reasoning.
For instance, perhaps this kid has a history of other similar incidents or has been a general menace to society in the past. I personally find the fact that he missed the court hearing because of a "misunderstanding" highly suspicious. Is it possible that the decision to have him tried was precipitated by other context factors omitted from the media story and not just the 70 cent Freddo?
Regardless I hope the case works out for the best and justice is duly and appropriately administered.
