1)Misinformation
Today, the media, once again, reported misinformation. The shooter was misidentified as someone else and his picture and name were released. This can not be undone. There have been other cases unrelated to shootings were reports, For example, Sage Mine disaster, initial reports stated 12 survived where only 1 out of 13 were rescued.
2)Martyrdom
Sadly, releasing the shooter's name will only create more violence. Think of all the shootings like today's. Do we remember the shooter(s) or the victim(s)? Do not allow sadistic criminals to become famous and you will see a lower amount of these heinous acts. Look at the motivations of the Columbine killers, They wanted to "outdo" Timothy McVeigh.
