Perhaps these short-enough-for-Twitter statements aren't ideal, because they can easily be construed as demanding retribution without due process. But the righteous indignation doesn't seem out of place. Not only are the killings themselves shocking, but the BBC alleges that the Cameroonian government was itself complicit in the cover-up by calling the viral video "fake news", and putting the burden of investigating its own military onto outsiders.

The BBC could have worded its closing tweet more clearly, but I don't think it's wrong for them to reiterate how rich it is for the Cameroonian gov't to make promises of fair trials when it seems to have done its damndest to avoid bringing justice at all.
