Turkey seeks arrest of Saudi crown prince allies in journalist’s killing https://www.cbsnews.com/news/turkey-saudi-arabia-crown-prince-mohammed-bin-salman-aides-arrest-jamal-khashoggi/
That would be unprecedented and opening of gigantic can of worms.
Many times in life we have to choose between the lesser of two evils. In this case I would recommend putting THE STIFF in the closet and letting it pass away quietly.
The ramifications involved of arresting the Crown Prince would be too long lasting and detrimental. Another words, let a lying dog sleep or Sleeping dog lie.
Many times discretion is the better part of valor!!
