Dorner, along with his manifesto, will be dropped into the memory hole. Along with the Christian/Newsom torture murders and other ghastly racial lash-out violence that doesn't fit the media template, it will never be mentioned again.
The media figures who supported Dorner - like Chris Matthews - will never mention his name again, unless forced to by the headlines of a particular day. If Dorner is dead, there won't be any more headlines about him.
Well, I take that back. It could happen.
If it comes out that he was encouraged or helped by other LEOs in the SoCal area, his name might rise to a one-day headline story nationally. That's the only way I see him grabbing national news attention now.
Even then its 50-50. If it turns out that he's part of a wide-ranging racist conspiracy among A-A LEOs, if it turns out that he has gang affiliations... I think it's completely possible that the MSM would bury the story.
I don’t see Dorner as having much at all in common the murderers of Channon Christian and Chris Newsom - those were impulsive, stupid, sane savages motivated by hatred of whites, and Dorner was a calculating, mentally unbalanced killer obsessed by personal grievance and perceived racist offenses against him - but he did not seem to hate whites as such, and he did not kill indiscriminately.
The leftist in the media just keep putting hay on the smoldering embers hoping to hide the smoke. Eventually, it is going to combust and be a much larger fire then if they would have just faced the racial killing and hate crimes of black America.
