Not talking about it and not publicizing it could be the best route for making them happen less often in the future. Monkey see, monkey do. The las vegas shooting has been plastered all over the news for two weeks. Everyone knows what the killer looks like and what his name is, but can the average person name even one victim's name? Media is all about ratings, but giving these all the attention that they get seems like it is just adding motivation to future psychos. Go out with a bang and get your name in the news.
