Easy, now, people.
There will be twelve jurors.
Some may believe that retrial after acquittal is always wrong.
Some may suspect the new evidence.
And some may be racists with enough brains not to make it obvious.
Which means there could be a not-guilty verdict even if they are as guilty as sin (and they are presumed innocent, let?s not forget that). And you cannot have a second retrial come what may. So I hope the CPS know what they are doing here.
