Today we hear that members of the International Cricket Committee have ruled that the now infamous Decision Review System (DRS) will continue to be used in the remaining Ashes Test Matches.
Whether or not the DRS leads to "better" decisions and fairer outcomes is a matter of opinion, of course. It can't be answered definitively. And the only people whose opinion matters on this are those committee members who were asked to pronounce on its continued use. If people don't like what they have decided, it's too bad. There is no appeal to a 'third umpire'. No technology to scrutinize their decision-making.
In any event, technology is incapable of replicating the ways in which those who made the decision perceived, interpreted and evaluated the 'evidence' before them. And it's on the basis of those perceptions, interpetations and evaluations that, in the opinion of the ICC, the DRS is deemed to be 'not out'. There is no 'reality' that exists in any way separate from the committee members' opinions on the matter - just other people's opinions. And those other opinions have no relevance to the decision that has been taken. it's down to them to decide. And decide they have.
