Ahead of the verdict, authorities banned protests at the court. Security forces set up barricades around the courthouse in Silivri, where the trial will take place, in western Istanbul, to tighten security. However  supporters of the defendants vowed to hold a demonstration. A group of 150 people gathering in front of the barricades protested against the court and tight security measures. Security forces warned to intervene in the protesters trying to climb over the barricades. Members of non-governmental organizations and several parties that are trying to reach Silivri were stopped by the security forces and later moved away to E-5 highway.  The moved away group waiting roadside are chanting slogans. Meanwhile police did not let a group of people who want to go to Silivri to attend the demonstration in Turkey's north western province of Bursa. There were also protests against the trial in Washington. A group of Turkish people dressed in black gathered in front of the White House with flags and black banners and chanted anti-government slogans suggesting the the trial was not objective.  The case began in 2007 with the discovery of 27 hand grenades in a house in Istanbul. Some of the country’s most prominent figures including former Chief of General Staff Ilker Basbug was detained and arrested, Republican People’s Party (CHP) deputies Mehmet Haberal and Mustafa Balbay and journalists, high-ranking military officials, have been jailed since then.
