Defacto it is "Guilty, even if some half brain dead befuddled jury can't see that the toe-rag is obviously guilty because he / she is a ____________
(Insert stereotype) and they would not have been on trial if there weren't guilty"
Rumpole used to have a saying about it better for 12 guilty to go free than to convict an innocent for that would be spitting in the face of justice.
However it seems to be
"It is far better to hang draw and quarter 12 innocent men and women, than to let one toe-rag off, for to let a toe-rag off would be to spit in the face of all Daily Mail Readers"
(Oh I do read the Daily Mail online, so I don't have to pay for it)
