And does not actually mean anything. Its like that "someone should do something" statement - what the actual fuck does that mean? What exactly do you think people can do?
I think for some people the crime is so horrific that, if there is no neat resolution, they have to find someone to blame. The police have failed (rather than they are constrained in what they can do). The government should be able to step in (into other countries where they have no jurisdiction). Or a family member "should have known", should have immediately believe accusations, should have acted with no actual evidence. And even when family members did everything they could, that they should have done more.
However, I do feel there is such a level of hatred for MM, whether it is racist, misogynist, xenophobic or the forelock-tuggers who want to uphold the RF loyalty at all costs, that she could have single handedly uncovered and brought to justice an international ring of child abusers and would still be accused of not doing enough.
Also really interesting to reflect on how many people posting about what should have been done actually know what the environment is like in those other countries. As a naive 19 year old backpacker, it took me ages to work out that the men I saw with younger local children were probably not all dads who had married a local woman. A walk though some red light districts in the Philippines, Thailand is a horrific experience - or at least should be for anyone with the much mentioned sense of morality on here. But if local police turn a blind eye, what do you think you can do as a foreigner?
