I remember there being a story outlining how his father disowned him, or something like that (if my memory serves me well), but this has escalated to a level I don't think anyone anticipated.
I can't imagine him being extradited, but that may be more due to hope and concern for his safety than anything.
It would be such a strange situation, seeing a high profile athlete being convicted of terror charges. However, in this circumstance (due to Turkey's not so pristine record), a conviction would not indicate guilt at all.
Strange strange world we're living in.
