The question you intended was "If there are details we do not know, is speculation productive?"
No, that is not the question I intended. -1 for the really obvious and inexcusable lie.
As an aside, (i) it did not happen in Apartheid South Africa.
(ii) I suppose that you would agree that not every death (Black or White) in police custody in Apartheid South Africa was as a result of police action.
Sure. Now are you willing to answer the question I actually asked, or would that take too much honesty? Stating that I meant to ask an entirely different question and then answering that one, isn't honest. It's frankly beneath you.
I am basically very disappointed by the lack of forensic thought in this topic - it seems to have been overtaken by liberal "right-on" political correctness, which is not at all helpful when a potential prison sentence is at stake; it sounds like hysterical mob rule.
The idea that the police story is accurate is no less speculation than the idea that it is not. In absense of data, speculating - but not concluding - is reasonable.
