Remember that reporter last month being shot and killed? Within hours her own father and boyfriend turned it into a political debate about gun control the very first time they came in front of a camera. How in the world could the public grieve for someone they don't know when her own family "seemingly" weren't grieving. The media is guilty of creating the fucked up world we live in. They are no longer just reporting the news. They're manipulating the news for whatever agenda TMZ style...
Well, I can't explain their grieving process, since everyone grieves differently.
As for grieving for someone you dont know, its a different type of grieving, when compared to grieving for the death of a family member or close friend.
