Well quite.
That certainty seems to be coming from a place of hope rather than fact, since no one knows the BKA facts. That's a fact. That position is not based on anything solid and really should not be used to try and browbeat others with different views into surrendering to what is a mindless 'guilty' mindset, as seems to be increasingly what's happening on here.
If we ever get to hear the evidence against CB and it's compelling and convincing, then I'll personally have no problem accepting that the BKA has the right man. And the reservations I currently have won't be an issue because I'll accept that what they have will be both compelling enough for me to put any niggling doubts aside and render any lingering reservations null and void. That's reasonable, isn't it?
Until then, I remain with you and others on the 'innocent until proven otherwise' fence.
