If the youths had their licenses suspended for 6 months (what a joke that is) then they must be old enough to have had licenses in the first place.

It's not explicitly clear, but I also get the impression that the killed and injured were participants in the stupid race, and not innocent drivers who were on the same road.

The case will probably be appealed, just like the Villagio case - and who knows if anyone will ever spend a day in prison.
