"Praise is flattery, artful, hidden, delicate, which gratifies differently him who praises and him who is praised. The one takes it as the reward of merit, the other bestows it to show his impartiality and knowledge."

There are a lot of hackers today, you know, and they perform their work in such a filigreed and delicate manner and they can show their "tracks" anywhere and anytime. It may not even be a track; they can cover their activity so that it looks like hackers operating from other territories, from other countries. It is hard to check this activity, maybe not even possible. Anyway, we do not do that at the national level.
