I have read that a Turkish MP has publicized that Sarin gas has been sent through Turkey to Syria, and that he is now wanted for treason.
I am from Germany, and in our law, it is treason ("Landesverrat") if you leak state secrets to the enemy or the public, with the intent to harm the F.R.G. or to benefit a foreign power.
Telling outright lies is not punishable under that law.
Now if I understand correctly, the allegations of that Turkish MP are vague and would have been plausibly deniable, which they are no longer if the Turkish head of state orders an investigation for treason as per the German definition of "Landesverrat".
Is the assumption correct that by ordering a treason investigation, Erdogan has given away that the story is true? Or what other "kinds" of treason are there in Turkey, that may allow for plausible deniability despite an investigation?
