Right after the Murrah Building bombing, after they caught McVeigh, they also caught a middle eastern man who was suspect. They let him go, and lady news reporter was livid over this as she believed he was involved.
I belive it is very possible that McVeigh had the help of the muslims in OK, in that bombing. JMO
I don't live in Oklahoma, but my husband was from there and I still visit relatives in the City.
