It ebbs & flows over the years but the amount of attention the issue was given after the shooting in CT seems to be more organized than what occurred after many such events in the past. Various politicians and the media have hung onto the topic longer this time than I remember previous events causing as well. Percentage-wise, less people own guns now than at times in the past and it's easier to demonize the minority so I don't see the issue ever going completely away. It may subside for a while but we are never more than one mass shooting from having it flare up all over again.
