There would have been no chance of a extradition to the United States since in your country he would have been threatened by capital punishment. A absolute no-no which is strictly forbidden throughout Europe. Germany and other European countries do not extradite to countries where the offender could end on a scaffold. This has for sure nothing to do with hostages.
