Oh yeah, that's right the information is suppose to filtered without any sort of mechanism in place to prevent it from being disclosed. Of course that would require journalists "conspiring" to not report that information, which would make it censorship just not gov't censorship. Or perhaps it would become part of journalistic standards (ie the NYT or AP style guide), but then again that would be a form of censorship. But lets just say that some how we can get around the whole censorship issue, we'll call it God's will or magic or whatever other way information could with held from the public without censoring it (although technically even if we put it on God or Wizards, it just means God or Wizards are the ones doing the censoring).
Still doesn't address the fact that regardless of the issue of censorship, the identifying of a killers beliefs doesn't seem to really have any impact on the division in our nation. Ie, I think most of us accept that mass murderers are mass murderers first with their "identities" coming in a distant second.
