How can you know they have already decided the result they want based on race?
You can't know this. You DON'T know this.
Heck, with me for example, you could not even know the result I want in this case, let alone why I want it. because I never, ever, even once said the result I want.
I don't pretend to know what you think ... but then I never said that I did. All I can ever tell you if what your words make me believe that you think. And I think it's very very clear that there were a good many people who pre-judged the case based on race. If you believe that is wrong then I have a bridge to sell you.
Can you appreciate that for someone to argue they think the decision is injust based on a whole number of racial equality issues and then turn round and say their opinion of the case is not in the slightest motivated by any consideration of race ... well, it is difficult to reconcile the two other than to believe that they are not being honest about one or the other.
I'm not saying that is your opinion. But it seems to be a viewpoint that is easy to find.
