I believe they did find Breukners camera and what they saw was true wasn't it?
What was true? That there's was some unequivocal evidence contained / stored in the camera*?
So why not charge him? Or, at the very least, interview him under caution?
HCW alluded to such very early on (4 years ago btw), and even went as far as suggesting that he didn't want to play his hand and reveal the evidence he had against him, as he would have the opportunity for revisionism.
A couple of things:
1. If HCW had such compelling evidence, then why haven't K & G stopped looking for MM? If anything they have dismissed the notion (of photographic evidence) out of hand.
2. HCW disclosed his evidence to SY. Why didn't they act? Why do they keep asking for and receiving funding to find someone who they strongly assume is dead?
3. Why did HCW get personally involved in CB's totally unrelated sex cases needlessly? Do they only have one prosecutor?
4. Let's say one of CB's hobo pals came up with the goods and led police to the aforementioned deceased canine. Stay with me. So HCW basks in the glory of finding a cache of dead MM images / video. Apart from this being the single-most significant discovery in the recent history of crime, it also propels Herr Hobo to almost mythical status - The Golden Tramp. And instead of letting him babble incoherently through days of ultimately doomed testimony and cross examination, he could simply have held him up as the paragon of snuff detecting that he is and simply proclaimed that he was, in fact, His Hoboness; the Fragrant Vagrant; The Visionary Vagabond; The Grifter Drifter with a Bifta.
But he didn't. He still hasn't disclosed the nature of this cache, despite numerous reasons why he should have by now, nothwithstanding the fact that it could have saved his now broken career. Why? It doesn't exist. At best he has a dead dog where something was, but it's useless whatever it is. It was a bluff. Look at how that panned out.
* I believe the cache found under Ken 'Diddy, No, Doddy' Dodd's dead dad's dead dog was alleged to be digital storage.
