Armenian genocide denial
Some countries, for example, Switzerland, have laws that punish people who deny genocides or crimes against humanity. A Turkish politician Dogu Perinçek was found guilty by this Swiss law in March 2007 because he said that the Armenian genocide is “a great international lie.”  He did not agree with the court`s decision, and he said that the decision went against his freedom of speech (the right to express ones opinion without legal intervention). He went against the court`s decision, and his law case went to the European Court of Human Rights. The court decided that Dogu Perinçek is not guilty and that this law is against the freedom of expression.
