My understanding is that because of Huck vs State, an accident scenario with KC panicking and taping over Caylee's mouth and nose after death cannot come in as a hypothesis (an unknown that might have happened to explain the facts). Florida's Supreme Courts have already determined a hypothesis of taping over a dead person's mouth isn't reasonable.
I think an accident scenario would have to be brought in as fact.
imo
The only evidence of an accident that I could possibly foresee at the moment is KC's testimony. Other than that, there's really nothing to suggest it that I've seen. Even if KC were to testify (oh please, please testify KC!!) there's still a lot of evidence that is incompatible with an accident theory which would put paid to that string of lies, should she choose to practically grab for the dp needle to inject herself by testifying.
The longer this plays out, the more discovery and discussion I read, the more premeditated this case seems, imo. Even so, remember that the dp is an option in Florida even without premeditation under the felony murder rules. That she was not indicted on that charge does not mean the jury may not be instructed on it, per Knight and the jury instructions discussed at length on those threads and the legal procedures threads. IIRC, every lawyer that weighed in on the subject agreed that the jury may be instructed on felony murder in this case and if they are and if KC is convicted not of capital or 1st degree murder but instead is convicted of felony murder, both the death penalty and lwop are still on the table as a possible sentence.
I don't mean to suggest that premeditation is irrelevant; again, I am convinced beyond any
reasonable doubt just based on the evidence/discovery available so far that this crime was premeditated. Just pointing out that even if the jury is not convinced of premed, as some posters are not yet convinced, that the ultimate penalties may still apply. Also remember that the jury will not have the luxuries we have enjoyed in isolating different aspects of the evidence/discovery for in depth discussion but will get the case all at once, so to speak. A + B + C + D + E + F and so on. While the duct tape may be a singularly damning bit of evidence, it is not the only evidence of premeditation and shouldn't, imo, be viewed as premeditation hinges solely on the duct tape facts.
It will be impossible, imo, to overcome all of the evidence in any credible way. Some alternate theory that may explain one piece of inculpatory evidence may thoroughly contradict an alternate theory that may otherwise explain another piece of inculpatory evidence.
