What does this say about the Greek Youth Uprising?

There is no media report about any dead police officer in the clash between the protesters and the Greek police.
But there are two confirmed reports about two Greek unarmed kids being killed by the Greek police.
There is no doubt that after the death of a police officer in the clash between the Anarchists and the police, things will be totally different.
In the last days I browsed some Internet sources and it seems that the Greek Youth Uprising has no direct organizational relation with any Anarchist Group. Most sources say that the protesters are huge crowds of Greek students accusing the Conservative Government of giving them bullets instead of social and sustainable support.

My opinion on the Greek, soon widespread European, protests

If you feel represented no more by the politicians in your country, you are in position to force the removal of those politicians or to claim the removal of the political system which has made them. In order to remove your government you should use mainly peaceful, non-violent rebellion. If the government uses the police or army force against you, you must use every means necessary to protect yourself from a repressive government.
This is what happens when a democratic government loses contact with the citizens!
In my opinion, the use of army force against your own citizens is indicative of the fact that you became truly totalitarian!

I truly believe that the Greek protests signal the last breath of democracy in Europe.
