I don't know why they would detonate it downtown either. It doesn't make sense that they would do it there. Good Lord, dare I think that islamofacists are striking in Oklahoma. Two bombs in two nights is just too much to be a coincidence.
Sorry if this has been posted before, but another website is saying it is confirmed that Islamic and jihad materials were removed from the suspect's apartment.
If that is so (and the other site is certain of this), then it sounds like the authorities are in "spin" mode. . .
