My opinions, watching as little as possible, from the perspective of someone who prosecuted for 12 years (2 more than Nancy Grace)...
1. evidence was pretty good that the child was the victim of a wrongful death. Murder, neglect, etc., not clear, but clearly a wrongful death.
2. Casey Anthony was a party girl who refused to let smoething as trivial as the death of her daughter spoil her good time.
3. Detectives caught Anthony in a web of lies. As I've learned, to many cops, someone who lies about a crime is guilty of the crime, whether there is actual evidence to prove it or not.
4. the prosecution jumped the gun in filing the bog charges without evidenec to tie Anthony directoly to the death, or more correctly, the cause of death.
5. Nancy Grace was right in that the law does not require that the State prove motive, but I've never seen a jury convict without some evidence presented on that issue.
6. defense counsel made the best argument you could, that Anthony is a terrible human being, but that does not prove she is guilty of the murder (which may or may not actually be a murder).
7. Nancy Grace and some of the other talking heads on television are the biggest problem with the criminal justice system at this time. proclaiming guilt before a trial starts, lambasting the jury for doing what they were suppposed to do and not simply signing off on the prosecutor's charges...I'm about as pro-cop/pro-prosecution as you get around here, and she makes me want to shoot my television.
As an aside, I truly believe that, in the end, there is final justice. Someday, in some way, Casey Anthony will have to answer for her role in all of this. We may not be able to watch it happen on CNN, but I believe it will happen.
