Well no, it stems from the whole innocent till proven guilty
No it doesn't and if you really believe that you need to have a word with yourself. Proof is formed from evidence and, to my point, sometimes the evidence doesn't need to wait for a court of the good unless you're PC. A load of jet liners crash into tall buildings, let's not conclude the likely as a court hasn't ruled. That is really your justification in such incidents? I am all for not jumping to conclusions, but not when to most rationale minds it's blindingly obvious once you get a broader perspective from those on the scene.
