I understand about not posting photos in here, because obviously it has affected people directly.
But to assume that the media will stop showing his photograph or details of his life is just unreasonable.
Everyone wants to put together pieces of the puzzle, to make things work out in their mind. As awful as it sounds, I've read up on Eric and Dylan so much this past year that I feel like they could have attended my school. I know of kids who were bullied in that way, and combined with a mental illness, I can see how easily someone can pick up a gun and kill indiscriminately.
Just today they had a Columbine survivor on Oprah talking about his work going around schools and informing them on compassion and tolerance. He admitted that a few students had come up to him after his talks and handed them their hit list, or thanking him for stopping what they wanted to do.
There's a fine line between abuse and advocacy, and I think at this point people just want to know why. Everyone wanted to know who Osama was after 9/11, who Eric and Dylan were after Columbine, who Lee Harvey Oswald was after JFK's assassination.
My suggestion is that you just avoid the news for a while, because nothing will stop the flow of free information. This is coming from a journalism student directly.
Edit: I see that people have already beaten me to the punchline, but it still stands.
Just turn off the news until the fever has subsided. Rely on friends and family for support or any details you want. They will be much more sensitive to you than any network can.
