I'm not at all sure that's true. It's definitely not true in the wider world. There are great disparities in how homicide of one group is treated as opposed to another. And this becomes even more obvious when one compares the media coverage. Look who gets lots of it and who doesn't.
It's true ON THIS BOARD. People who post on Babble are not part of anyone supposedly having "control of the media". No one's pain is being privileged over anyone else's in this thread.
