Now, I perhaps am guilty of this as much as anybody, but it's concerning me...
There are a number of threads and statements that use some quite definitive terms like 'proof', 'must', 'did' etc. It's made worse when you see the evidence to substantiate it, and it rarely 'proves' any such thing.
I think it's incumbent on us all to accept that a great deal of the evidence is open to interpretation (and by very nature of this case still be debated, it only serves to add weight to that suggestion).
I don't want to be politically correct, I couldn't care less. And I don't want to sound like a politician or counsel - but I do want to work with absolute logic and only use the words 'Proof' when it is irrefutable, or at least beyond the realms of wild improbability that something else happened etc.
I believe at least 70% and possibly as much as 90% of statements that "proof that sheila did this..." or "proof that jeremy said that..." are simply wrong.
Can we try and be true to the evidence, even if we are overwhelmingly convinced personally?
A good technique is to pretend you're arguing for the 'other side'. If you can't find a weakness in your argument (and therefore can't think of what the other side will throw at you), you PROBABLY haven't done a good enough job!
