>> In spite of what the media, and even our own government is telling us, this act was not committed by a group of mentally deranged fanatics. To dismiss them as such would be among the gravest of mistakes. This attack was committed by a ferocious, intelligent and dedicated adversary. Don't take this the wrong way. I don't admire these men and I deplore their tactics, but I respect their capabilities. <<

"Mentally deranged" can take many forms. One F'ed up area will not necessarily affect another.

I suppose some people are just genetically or paternally predisposed more or less to force their world view via bombs and death. Whether you call this "deranged" or not is only a vocab issue.
