France World Media Coverage and Africa None ?

You know at first I was just telling my self, that a tragedy is a tragedy and I am right, but the way some lives are potrayed more valuable or important in the media bothers me ! I feel for all humanity equally but a lot of people I am not so sure ? I know " France " is a bigger story for ratings and " Politics " reign but to be so obvious in there bias media coverage is shameful ! Now I know some people may say, I am only talking about this topic because I am an African American but I have been paying attention to social media post about the bias and that is a story init self ! I wish some one would explain to me from the media, why coverage on one tragedy is more news worthy or important then another ?
