There have been hundreds of acquittals at the Old Bailey and the other London Crown Courts over the last 30 years where the defendants were on legal aid - It appears to me that you are promoting your own narrative, for whatever reason, by making stuff up - as in your description of the victims Mother as ‘so called’ and a ‘Slack Alice’. Where will l find the evidence that the police evidence was altered and the detective in charge of the investigation was crooked. Did the Detective in question stand trial? were they convicted?
Can you point us to the relevant newspaper reports or Court reporting?
There is a phrase that is applicable in this instance “Put up or Shut up”.
Of course miscarriages of Justices have and do occur - It just seems to me that you are lacking in any factual information to support your story.
