I totally agree with your reader.  It feels like almost a taboo issue to discuss and I held my tongue, but it seems like this discussion really needs to be centered around the execution of Lawrence Russell Brewer.  It's hard to deny that Troy Davis is an easier fight, but we as a country that executes people really should be asking ourselves, "If we really want to abolish Death Row, shouldn't this monster Brewer be the one we should be convincing ourselves we need to protect?"  It's much grayer waters to tread in than Troy Davis...

Another sees black and white:

I don't really consider myself a supporter of the death penalty, but to answer your reader's question about Brewer - yeah, he deserved it.
