Why the NOTW's sting was justified

In the Guardian, Roy Greenslade explains why he thinks the News of the World sting which led to the breaking of the spot-fixing controversy was justified.

Was there a genuine public interest in exposing (alleged) sporting corruption?

I like sport and I like cricket. I support Essex and England. I understand the desire to win and the passion it arouses in both players and spectators. Sport is meaningless if it is fixed because it is, at its heart, all about competition. Otherwise, there is no point to it.

People who do not like sport may well take a different view. They may see it as nothing more than a branch of the entertainment industry and, as such, fixing what happens is no big deal. So where, they might ask, is the public interest in exposing it? Though I have also grown increasingly cynical in recent years about corruption in sport (such as the use of performance-enhancing drugs), I cannot agree.

I do believe that there is a genuine public interest in exposing sporting corruption (though I readily concede it's less important than, say, political and financial corruption).
