In my mind there is no question here; public media access should be allowed for all non-security-dependent scenes and attacks. We must be informed to act and react intelligently. I fully understand the need for some silencing and censorship where media scrutiny would threaten national security, but in general, the media should be allowed to report on everything and anything. If we have wide-spectrum censorship of terrorism and attacks, we lose our sense of reality in favor of rose-colored glasses; this is one element of the 9/11 attacks, since we had never been directly attacked and had no concept of how it could work. Most media coverage of terrorism took pains to show how far away it was and how "it could never happen here." With fuller coverage and better understanding of the real worldwide risks, we could at least have had better public knowledge.
In short, no censorship.
