Hi Neil, I think the question is, why are you pointing to events that are a result of a local aberrancy, and that have almost zero public health implications, but which certainly make for uncomfortable reading among Tanzanians? ("Another child murder in Tanzania, apparently for witchcraft (?traditional medicine).")
To give you the flavour of that, imagine someone posting news about the Polish people being murdered or assaulted in the UK post the Brexit referendum vote. You can even phrase it the same way: "Another Pole murder in the UK, apparently for immigration reasons (?Brexit)."
Let's stick to the big picture!
