As Malcolm Coles relates on his excellent piece about it,
In their attempt to be first with the verdict on Amanda Knox, the Mail Online published it's pre-written story the moment the judge said the word guilty.
However and a lesson to all journos out there,listen to the whole thing
Unfortunately, like many people, the Mail was caught out by the judge finding her guilty of slander - before clearing her of the murder. At the sound of the word "guilty", they hit publish on a story about her appeal being rejected that includes reactions from the family and prosecutors being delighted - reactions that can't have happened as she was found NOT guilty of murder.
