Local and federal law enforcement agencies should adopt a new policy of withholding the name of suspects arrested for mass killings for a period of 6 - 8 weeks. The 6-8 week timeframe would serve to allow the news cycle to shift so that the assailant does not receive the wall-to-wall media coverage that they are seeking when they commit these acts. I am not entirely certain whether or not this would violate the Freedom of Information Act, because the information would be available eventually, just not immediately after the event.
The primary motivation for psychopaths to commit acts like these is notoriety and fame, end of story. They are very much like the child that acts up in class and is continuously scorned by the teacher. They don't care that it's negative attention, they just care that it's attention at all. We should not indulge maniacs like the deranged individual responsible for the Arizona shootings by giving them exactly what they wanted: a platform to force-feed the world their idiotic points of view and all the famous people on television repeating their first, middle and last name.
Just an idea.
