All the media attention and witch hunting by the media and the intense focus on Casey Anthony's inappropriate behavior reminds me of the
Azaria Chamberlain case, in which a young mother was convicted of murder after a dingo snatched her baby and she didn't
behave like she should have afterwards.
Relying on strange behavior to justify a murder charge is very, very dangerous ground, and Casey Anthony's behavior is certainly central to the prosecution's case.
On the other hand, she should be convicted and pay the penalty if she is guilty.
It is unreasonable to demand CSI-like evidence in order to convict someone. That show's ability to get evidence is really annoying (My pet peeve is their ability to magnify a single pixel reflection on a grainy photograph into a high resolution photograph of the murderer.) and I've heard that it is a real problem as some jurors just won't convict without that kind of evidence.
The standard for conviction is no reasonable doubt, not absolutely no doubt whatsoever, which would basically be impossible to meet ever.
So, I'm glad that the jury is deliberating carefully and not rushing to judgement. It can't have been a good experience, either to have seen all the evidence or to have been sequestered for so long.
