I've read your posts in both threads and it's clear you are fixated on race issues. My take on the difference that you seem to be overlooking as it pertains to media coverage is pretty simple...they seem to be more prone to covering shootings where all the victims seen random and are strangers. A lot of black on lack shootings tend to be crime related and retaliatory between parties who know each other (ie not just randomly killing people or living out some fantasy)....
No value judgement, people who shoot and kill other people are generally just shitbags...I think the media, and public at large, generally just find random acts of violence (like this dude in Buffalo) scarier than non random beefs that end in murder, thus they cover the former more.
I'm sure there is an element of race involved, but you're fixating on it to a degree that doesn't make sense given what I've explained above as an alternative explanation.
