I don't know if that is a case of misreporting and/or bad headline writing. Or if this "veteran criminal lawyer" truly doesn't understand the law but that information is just plain wrong. The standard of BARD only applies to the evaluation of the evidence as a whole and not individual aspects of the evidence.

If the lawyer really said this, it's an example of why the public is often suspicious of defence lawyers and their machinations.
