I remember a comment that Sue Klebold got a better reception from the media because her voice sounded like it was an NPR anchor's herself.
That meaning she could have a rapport with her interviewers and possibly be seen more sympathetically.
I know there are other comments about how she's a hypocrite or how she throws the other killer under the bus, but I think she is fair as she can be, being the mother of one of the killers. But maybe I'm sympathetic to Sue Klebold because of her demeanor.
