From what I see, If the prime minister of Turkey is democratically elected, then he can run his country the way he wants. We from outside can comment, but judgment is reserved for his electors only. People have a democratic right to non-violent demonstrations, but looking at some of the tv coverage I could see angry turks throwing stones and molotov cocktails at the police. Obviously with a degree of tolerance, the authorities can wait for tensions to calm down, and how long this takes depends on the police and ultimately the government in charge. I think the turkish authorities have done well playing this out for so long - 2 weeks. In similar situations in the west, I'd doubt if they would have waited so long.
