Sadly I think that it could go either way and there's a good chance that he's going to be found not guilty on all of them.
The only thing that might help is that he said sorry in response to the animal accusation. You know what I mean. Own goal there on his part.
AND I'm sad to say evidence from other men saying he'd been erratic.
No doubt that the defence will make out that they're jealous of him or something along those lines.
The first accusation of PIV rape may be believed by the jury. The anal rape one may not be.
On balance, I think he's guilty on all of them.
