Is the judge pointing them towards a not guilty.
He made the point, correctly, if they believe there is a risk the fibres found on the defendants clothes were transferred after the murder then they should acquit.
He then went on to say that the woman who did the forensic analysis and studied the storage patterns and the risk of cross-contamination and eliminated it may have a vested interest as it was her company who found this latest evidence. Not even the defence stooped that low.
However for all out there who claim this is a stitch up and a show trial the Judge and his comments show this is clearly not the case and these two people are getting a fair trial.
