Actually you can do that perfectly. The Turkish law doesn't allow it, she does it on Turkish soil, she can be arrested for committing a crime in the eyes of Turkish law. No matter how severe the crime is. Usually in these matters the journalists are being released from prison fairly quick to not inflame international political damages.
And that last remark is just silly.

Agreed, but that's besides the point. Freedom of speech doesn't exist any longer in Turkey either.
