As far as I know, a person awaiting trial cannot even profit from this... but I could be wrong. I think the author is the only guy who stands to profit. Do you think a media guy who's supposed to be impartial and continue to report objective issues surrounding the case would EVER share profits with those who may be convicted of capital murder.. ? Uh, nope.
I'd say that if Ron were to ask Glen, that's exactly the answer he'd get, unless the author were to lie about it. I can't see any way that this would work for Glen, the Review Journal or the case/ justice itself, if C&K were to profit.
