Copycats ... thanks to the national media, the shooter is famous. We'll remember his name long after everybody forgets the names of the victims. And so people are so desperate to be famous ... they don't realize (or don't care) that there is a difference between famous and infamous. So they'll do anything for attention.
These killers know they will get a perverted form of immortality. The same with the nuts who shot Lennon, Reagan and others. They get a notoriety they would never have achieved in life. The media does not help things by continually to make it front page news. They are not to blame but they should cut down on the sensationalism. They won't cause it sells copies though. To these folks bad news is good for business,
