Two different issues here. First, free education is not a good idea in and of itself. The idea of being institutionalised for a few years before you can enter the work place is an old one and it's no longer relevant. I disagree with the idea of free education.

Secondly, an idea with which I wholeheartedly agree: The undemocratic protesting must stop. It doesn't matter what you are protesting about, if you feel the need to kill people or shut down institutes or damage their property, then frankly I don't care what you are protesting but I don't even want my taxes to keep you alive in prison. You are not civilised and you do not belong in a civilised society.
