I think right now it's fairly obvious the murders were spurred on by either racism or religion. You and others can just take the killer's word for it and leave it at that. I guess the idea that a mass murderer would lie about his motives in an attempt look to avoid the death penalty is a foreign concept to all the experts here.
So there's no ambiguity you're positing the guy that murdered 8 people is going to avoid the death penalty? Dude better start coming up with WAY better "lies" for that to fly.
