Why sly, Roch? I'd feel more inclined to agree if we were in the pre-trial period. Certainly the series will bring the case to new people, but do you REALLY believe every one of them is a potential supporter? I'm guessing that if a poll was taken the ratio of the result would be roughly that which the jury bought back. There'll always be some who'll refuse to bring in a guilty verdict.
It's sly because they know exactly what they're doing.
(1) Allow a program to be commissioned.
(2) Shut out the defence entirely.
(3) Use the airing of the program by allowing McKinstry, CAL, The Sun etc. etc. etc. to piggyback on the production.
Public opinion is key in this case. The more dissenting voices, the worse for the authorities. The less dissenting voices, the better for the authorities. And as for the split, I would have said at best 60/40 in favour of guilt among the population who had any inkling of the case (prior to the drama).
