It's not just not the mainstream media onto it. Even the dedicated UFO gatekeepers haven't touched it yet. I think that indicates that: it's factional, and it's a new faction.
Paraphrasing this guy: "The story is bigger than Snowden. It's just breaking and mainstream media have had a month lead on it, been approached, but refused. It should have people writing to their representatives to investigate Gursch's allegations. People should be outraged at the criminal activity that has gone on outside of oversight. Media is complicit so far."
