I think the fact that the Feds have gone public on NYC, but still are silent on Norman means there's still a treasure trove of information in Oklahoma that they don't want to get out and there are probably some people they're still keeping an eye on. The question of why he would leave behind so much evidence behind and still go to the stadium and blow himself up prior to the execution of the NYC plot is still quite puzzling.
Actually I think nobody cares cause Oklahoma is the middle of the country. We have to fend for ourselves. Sickening.
It was an accident he blew up by most accounts -- he had no intention of blowing himself but placing his backpack to do the maximum amount of damage when it blew up. That second backpack had to have an owner. Was it going to blow up when people came running out of the stadium?
