I see that "Florida Child-death File" is coming out with some high-end idiocy about the Anthony case. The simple fact would appear to be that the jury didn't believe that it had been proven beyond a reasonable doubt that Casey Anthony had any direct involvement whatsoever in her daughter's death. This is clearly seen in the acquittals on both the murder and the manslaughter charges.
Some idiots (including a paralegal) are trying to suggest that the acquittal might have happened because jurors were reluctant to send Casey Anthony to the electric chair (or lethal injection). But that's a ridiculous claim: firstly, the jury had the option of manslaughter, and secondly there is a sentencing phase in the US following the verdict (different from UK courts where in a murder conviction the judge announces the sentence directly after the conviction).
Therefore, the jury could easily have convicted of Murder 1, then asked the judge for compassion in sentencing and recommended life without parole. Of course, the judge could disregard the jury's recommendation and impose the death penalty, but AFAIK such an override is unusual, and also the jurors could feel absolved even if their recommendation was overruled.
A Canadian idiot goes further, and tries to make the ludicrous claim that the jurors all thought Anthony was guilty of murder beyond a reasonable doubt, but acquitted as some sort of demonstration against capital punishment. He then goes on to boldly state that Anthony is as guilty as hell, and that she's "got away with murder". What a damn idiot.
And that is the end of my comments on the Casey Anthony case.
