Granted it's always a media circus for obvious reasons. But this happens to be the second largest fatal school shooting in U.S. history, and it involved children. Discrediting a handful of peoples sorrow with your "world total" statistics is pretty lame. Instead, how about showing some tax returns from your major contributions to St. Jude, or a picture with your ID next to it, of the child you sponsor at Feed the Children before you pass judgement.
If you want to chastise someone in the midst of this tragedy, I'm the wrong guy. Have a look at Christian fundamentalists exploiting and politicizing the situation, using it as leverage to proclaim that separation of church and state is a mistake, that video games cause violence, and so on. Have a look at ultra-liberals and reactionaries calling for strict gun control laws and other stopgap measures to serve their ongoing agendas. Have a look at the media, exploiting the tragedy for the sake of their ratings and giving the killer the recognition and infamy he desired, quite possibly encouraging the next mass murderer with the knowledge that he'll be immortalized too. You might even take a look at feminists, whose never-ending women-first politicking over the past decade and a half has pervaded our society with misandry, greatly contributing to the disenfranchisement of young men.
I'm not discrediting anyone's sorrow, and I'm not exploiting the situation. I sympathize with the victims' families. It's just that I'm aware of dying children EVERY DAY. I may not think about it every minute of the day, but it's there in the back of my mind. I've been visiting these gore sites for eight years, and that's half the point of coming here... to be the type of person who DOESN'T ignore these tragedies most of the time. Most people just ignore it all until something terrible happens.
