I didnt watch the video (2 hours? No thanks) but I think the judge made it clear that the primary witness gave unreliable and untrustworthy testimony which really sank her credibility in this case.
It hit peak head shaking wonder when the Crown prosecutor argued that just because she was sucking on a guy's johnson doesnt mean she was consenting to other sex acts? Specifically "You cannot treat that as a communication of consent to any other sexual act." Which means, in that lawyer's world, one must ask consent to every individual act.
Does that include changing positions good sir? "Uh, just because I did doggy style doesnt mean I consented to reverse cowgirl. How DARE you assume I consented!"
Hmm, I get the impression these people have never actually had a sexual relationship? Probably just safer to print out a consent form for each act and then have both parties sign before each act to make it clear they were both ok with it. I heard that works /s
