This is a perfect example on how the James Bond turff aka The Floors work. In this trial even evidence based on assumption and conclusion was taken into account. But this is international turff...
In Germany the Floors are all populated by Nazis. They are direct profiteurs from Nazi rule and there is no excepetion. The entire nation was build up and is run by Jewmurderers.
In their Floor world they need not that much effort to hide proove and this way believe that they easily can go for the perfect crime. Evidence decisions as on international turff based on logic are no happening in any German court and as soon as on the BKA internal lists you'll face with prosecuter judges that also enforce their sentence telling you that you lived from berries while having lived in the Frankfurt woods, because he sais you an the carracter joining the French Forigne Legion.
Point is....there will be no tial in an underground war. You will just wonder who is gonna kill you. Me, FSB, IRA, ETA, ANC, PKK, Kartell, Hisballah, Iran, China, your son .... fuck you Germany...but hard
