Total speculation here, but suppose there is a bio attack. 70,000 fans ingest a highly toxic substance that is pumped in through the HVAC system. By the time they realize that they've ingested something, too late to do anything about it. In the mean time, millions of people are watching the horror unfold on the tube.
I want to believe that the latest EOM post is just part of one big hoax, but there is something about the last three EOM posts that makes me think there is something real. If EOM is trying the scare the infidels then why post on on a BB that only a few thousand people read, as opposed to a BB hosted by a major media outlet. Better yet, forward the messages to Drudge or Hannity for maximum exposure and panic. What also bother's me is that the last three EOM messages seem targeted to the Jihadists, as opposed to earlier messages, which were geared to the infidels.
