The Casey Anthony jury reached the correct verdict. The question put to the jury wasn't did Casey Anthony kill her daughter Caylee Anthony, but did she deliberately carry out a plan to murder Caylee by suffocating her with duct tape.
The jury didn't buy the prosecutor's claim of premeditated murder and its easy to understand why they might have rejected it. When I first heard of what the prosecution was attempting to do I thought they had a difficult, if not impossible, task before them.
I could believe that Casey got frustrated because she couldn't get her daughter to shut up and covered Caylee's mouth with duct tape to keep her quiet rather than to kill her. Casey might have positioned the tape carelessly or the child might have had a stopped nose with the end result that Caylee was unable to breathe and died. I have difficulty accepting the claim that Casey is mentally capable of planning to kill her daughter by using duct tape to suffocate her.
Casey was unable to accept responsibility for her action and tried to cover it up. Perhaps she had difficulty admitting to herself what she had done.
American prosecutors suffer from a "disease" which causes them to try to present every wrongful death as premeditated murder. Perhaps prosecutors feel they get better publicity if they convict an evil killer then if they convict someone for doing something stupid.
I don't know if Casey Anthony caused her daughter's death or not, but it would be unfortunate if she will go unpunished for the death because prosecutors made the mistake of trying to turn a tragedy into something sinister.
