I've made several 999 calls, unfortunately, both as a witness and a victim, and I'm fairly sure I mentioned the race of the individuals concerned in all of them. Ask me now what they were wearing and I don't remember in detail: the simplest facts about them, like skin and hair colour, are what come to mind. So, no, I don't imagine it's unusual to focus on that. In fact, I would think that 'a [insert skin colour here] man is attacking me' is quite a common thing to hear on a 999 call! Those are very salient and easily memorable details, and they're the kind of thing you can spot even in poor light conditions or when there's a great deal of confusion.
In any case, you seem to be conflating the behaviour of the murderer and his brother, who did lie about a racist attack (but no one's denying that), with that of the police, who you're claiming only handcuffed Novak because of that accusation (or only handcuffed Novak because he was white, which is what you would actually need to prove in order to sustain the claim that the police were racist). But, again, there's no reason to believe this, unless you think it is unusual for police to arrive at a scene and handcuff the person who multiple witnesses are pointing at and saying: 'that's the guy who attacked us'. Imagine if the racial aspect of the situation were inverted, or if all three had been the same race. Would the police have behaved differently? I find that doubtful.
Yes, and I brought it up because it's a key piece of evidence. You seem to agree; however, it doesn't demonstrate what you claim it does. Indeed, that's why I brought it up - it supports my point, not yours!
I haven't and I don't intend to. I have read several accounts of what happens in the footage, including the judge's description from the sentencing remarks. As long as those descriptions are accurate to what happened, it won't effect my line of argument that I've not watched it.
