The situation in Turkey is not just another free speech banning law, making law maker and enforcers looking ridiculous. Not at all. There is a mindbogglingly huge corruption scandal going on. The prosecutors were removed from the case, police were ordered not to obey court orders, tens of thousands of civil servants have been relocated etc to stop the investigation. The extend and the number are both unbelievable, so I will leave it to look them up yourself (you would never believe an anonymous source on internet talking about 12 digits, would you?)
Now, when it became apparent that the prime minister had no intention to actually let courts do their job, the prosecutors (quite unlawfully) started leaking dozens of voice recordings of their evidence. So far we have learned that Mr. Prime Minister ordering newspapers what not to press, ordering his son to move hundreds of millions of dollars from his house, selling valuable land to his friendly businessmen, using tax law to crush unfriendly businessmen, ordering the police to increase tension during Gezi movement etc. Tomorrow is the big day. It is said that the PM will not be able to keep his post no matter what after the recording posted on 25th of March. The leaked tapes so far has been uncovered PM's behavior so unconstitutional and immoral that I cannot image what could possibly be so much bigger. The expectation is that either PM's ordering assassination of a opposition leader or he having sex with a minor. Whatever it is, it got PM panicked. This is what got actually twitter banned. There is a cover story, but it is so hastily constructed that *the cover story itself is unlawful.* The story is that a court banned twitter on for not complying, a court which is not authorized to do so, and a court which denies doing/trying to do so.
So whatever your ideas on different lands having different customs and laws, this is not the event to discuss them. Twitter ban in Turkey is 100% wrong.
