I don't see how you can be for or against a cause in a country you might not know what the social situation is about, and how things have been for the past 20 years through several administrations, you're passing judgment on these rioters, claiming they are something they are not,
since most those kids don't have internet, and I'm not saying they are deprived because of that, but don't go and equate them with a certain group of young culture that you might be familiar with, just because that's what comes into your mind first, makes you look very ignorant. Plus cursing them out doesn't help your cause.
You also asked for links as to prove the police brutality which I have personally witnessed. Well here's some videos, I can't find any specific articles/videos/reports on the things I witnessed since this was back in '96-'97. Keep in mind none of the videos have anything to do with the current turmoil, as to demonstrate why so many people in Greece have such animosity towards the police, also be sure to read the side info from each video which gives some insight as to what is going on.

This is a video of two Albanian immigrant teens and what they had to go through during their arrest, and these are supposed to be professional police officers, and the next one is of an Asian immigrant and the abuse he had to go through:

Bottom line is I know what I saw, and I've lived through it for some part of my life, I don't really have to prove it in a forum, or get into a fight and heated argument with you as to attempt to prove this. All I'm saying is that, don't be so quick to judge and label people as "slime-balls", and criticizing their actions so severely when you might not be as familiar with the overall situation as you might think.
