Oh brother. If you can find a peer-reviewed journal article that claims that the Murrah building wasn't brought down by Timothy McVeigh, post it. You'll excuse me if I'm swayed by the internet postings of someone who's not a structural engineer.
Who do I believe? A Brigadier General in the USAF or some internet crackpot who thinks that DHS has been serving warrants on Muslim compounds? Tell the people who live near Islamberg, NY that they do. LOL
