Two things already mentioned but which need emphasising:
1. In common with all such reports, we have a seen few paragraphs to explain the outcome of a court case which probably lasted a couple of weeks or maybe more. Quite telling (with regards to the “guilt by association” criticism) is this from the judge (who presumably was privy to all the details which we don’t have):
“But the judge stressed: ‘The defendants were not in a joint enterprise; they were each principal parties playing a full role in committing the offence of a criminal conspiracy either to kill others or to intentionally cause them grievous bodily harm.’ “
From the few details we do have it seems clear that all the defendants were involved in quite a reign of serious violence. That may not be what they were eventually convicted of, but it adds to the evidence that convicted them of conspiracy.
Of course it’s a racist decision because the defendants are black. Life’s a bit tough sometimes. But it doesn’t get any easier if you roam the streets with machetes threatening to kill people.
