Definitiv die Central İntelligence Agency ;)
Und wenn du dich an geheimen Forschungen und Geheimdiensten interessierst kann ich dir nur das Buch "Die Pyramiden und das Pentagon" von Nick Redfern empfehlen :))

To carry phones to school is important because everybody has one. Everyone uses one also at home and at school. As we all know it's forbidden to use phones at school and we should put them off. Ok, the school and teachers want the best for every student and because of that it is understandable... But what, when something happens like ur mom is going to die or there is a emergency ?
İ think its okey to let the phones putted on without surving or being always with it. They should'nt be angry with the students seeing them hanging with their phones... Not always.
