Indeed he did!
It looks like they may have to prove premeditation. As you'll recall they were unable to do so in the last trial, which otherwise went so well for the prosecution. The motive they tried with hashish and comic books didn't go down so well with the Supreme Court, thus I'd guess that one would be out. I'm
just guessing they won't go with a satanic ritual-orgy.
I don't think the 'rape prank' is going to cut it either, would one set up such a convoluted alibi for something that was supposed to be for fun? I doubt that would work with the Supreme Court either.
So...what kind of motive could be proven? They have to account for the fact that Raffaele's must have set up his computer to give an alibi, or that they put in a video to do the same and got back before it ended. I suppose the only other thing that might work is if they 'spontaneously' decided to go kill Meredith during their movie. That would be "Stardust," right? I've not seen it, but it looks like it's pretty lovey-dovy schmaltz to me, is this sort of thing that inspires murder?
