Opinion:
I believe the state prosecutors should not continue on with the case, since they stated that they were "suspected" and according to the text, no liable evidence was found for them actually trying to procure an attack on the public facility, unless admitted by the suspects themselves. Plus, they are 15 and 17, and if they did admit to the attack on the facility in the Aschaffenburg Area, since it did include the use of firearms, it is up to the court to decide to put them in a Juvenile Detention Center or Prison.
