I haven't practiced in a good number of years, and never practiced criminal law, but from memory and law school:
1. I don't think their testimony would be helpful (probative) as to JA's guilt. The tapes deal with information their opinions of Jodi after the fact, not to do with her planning and execution of the crime. This type of evidence is marginally relevant and probably unduly prejudicial. Theoretically, JM could call them as hostile witnesses, but he might not want to do that for tactical or strategic reasons.
2. Depends on the statute of limitations, but they definitely could, regardless of the outcome of the criminal prosecution. As we saw with OJ, even an acquittal is not a bar to a civil claim of responsibility. It is much easier to win a judgment in a civil suit than it is to get a conviction because the burden of proof is significantly lower (preponderance of the evidence v. beyond a reasonable doubt).
3. Depends on state law. Many states do have a prohibition on convicted criminals earning income from the crime they committed. I think it's called a Son of Sam law (from the infamous NY serial killer) after he attempted to profit from his crime. Some states may have ruled this type of law unconstitutional, since it may abridge the convict's first amendment freedom of speech, so they are narrowly tailored so as to not infringe on someone's right to tell their story.
I haven't researched my answers...so sorry in advance if they are confusing or inaccurate in any way. HTH:twocents:
Thanks.
Always good to have an answer from an atty.
My Qs to you are RE Q3. And my answer was that the state can not bar someone from writing the book, only that profits from the book are taken. Thus not voiding 1st Amendment. And also states that have such a law--don't they mandate profits be given to the victim's family?
