Thanks for attempting to clear this up but that article doesn't do it. Why would a ticket taker ask someone coming from inside the stadium about the explosion outside the stadium? That makes no sense.
This is a very important point. As are those regarding the material taken out of the BlownUp's apt and car. And the allegation of an attempt to purchase ammonia nitrate at the store.
From what I understand Adam Smith was outside the stadium and was recruited by LEOs to help divert the crowd away from the crime scene. The part about "as he was leaving" isn't correct according to the taped interview I saw with Smith initially. (I think it was on Ch. 9, but not sure...).
The Ammonium Nitrate attempt to purchase was confirmed by OUPD and the owner of Ellison Feed & Seed (I think that's the name of the store). You can check out my summary, and links listing on my blog for more details as I don't have the time right this moment to retrieve it all. (sorry!) (o:
The AN has been documented over and over on these threads and in the local news.
