If you bother to read the whole thread you'll see that the preferred route was via police and fair amount of investigation was undertaken and then presented to them.

The police's 'inability' to pursue the case coupled with the discovery that the possible perpetrator was connected to some kind of twat who could possibly exact 'revenge', when weighed against the financial costs determined the current course of action.

Or, to put it another way, butt out - von has sorted it his way.
