Any lawyer or judge will tell you that there has never been a jury that could possibly be described as "qualified."
Every case I've tried has had a qualified jury. THey are never as good as you'd like to have and never as bad as they could be.
The technicality people remember is that he was convicted of first degree murder under the felony murder statute only to have that thrown out of by the supreme court I think because the underlying felony was a lesser included offense that they said it should merge. That left the new jury with the option of voluntary manslaughter and 2nd degree murder.
The point of the qualified comment is that people, especially those who disagree with a verdict, tend to second guess juries but that fact of the matter is that they are the only people who don't have a stake in the matter who've heard only the admitted evidence, nothing more and nothing less. People outside question "how could they do it," without actually being in their shoes, while having their own opinion colored by all the extra information that appears in the paper, opinion pieces they've read, the hiding of assets they've read about, and the running off to Brazil. When in reality none of that is relavent to whether he was guilty of second degree murder or voluntary manslaughter. The judge decided that Lyon's past behavior and emotional issues were relevant, but not definitive to the case. And yes most likely the guy is going to hell. Or at least we can hope so.
