It's hard to know exactly what's going on between Today Tonight and A Current Affair - especially if, like me, you prefer SBS's World News Australia over both of them. As I see it, though, it boils down to this:
Naomi Robson has entered Papua on a tourist visa when she's really there to film a story and "rescue" a boy from being eaten by cannibals. The story about the boy originally screend on Channel 9, which is saying that it wanted to rescue the boy but was advised attempting to do so would only make things worse. (I'm not sure what's worse than being eaten alive, but that's what the Nine people are saying.)
What it comes down to is that both TT and ACA are driven by ratings and neither of them by a desire to really make a difference or to serve their viewers with an actual news story. If it had really wanted to save the boy - and the legality of doing so is highly questionable given that they are operating in a soveriegn foreign country - Channel 7 wouldn't have sent Naomi Robson there, because she was always bound to attract attention. For its part, Channel 9 is just point-scoring. Shame on both of them.
