We've all seen the recent cases where celebrities have been in Court charged with a variety of offences going back many years and one of the things said by the accusers and Prosecution is that "so many people couldn't have got it wrong"?

Now we see in the Pistorius trial in SA completely the opposite.:-

The judge in the Oscar Pistorius trial has questioned the reliability of several witnesses in court, as she delivers her verdict on the athlete.

Judge Thokozile Masipa said humans were fallible, and may not have heard gunshots or screaming as they thought.

OK, it's different countries and different circumstances and whatever the truth of the matter, it just goes to show that the most unreliable evidence is that of "eye" witnesses and what they say.
