Not since the O.J. Simpson trial has there been such interest in a court case as there was in the trial of Casey Anthony. Americans across the country took to Twitter and Facebook to generally voice their displeasure that Anthony was found not guilty on all of the major charges.

Although many people were shocked and angered by the decision, they really shouldn't be.

Even though one might think that Casey Anthony looks guilty, that's not the way our courts systems work. You cannot simply convict a person of murder, and potentially sentence that person to death, based on purely circumstantial evidence.

Does Anthony look a bit guilty based on her series of different lies and pictures of her partying shortly after the disappearance of her daughter? Absolutely, but that is not enough to convict someone of murder.

It was easy to get caught up in the excitement of the case and believe Anthony to be guilty based on what was seen on television, especially if you caught even a minute of Nancy Grace over the past few months.

But each juror had to consider the case a bit more carefully than your average American sitting at home following the trial on Twitter. Each juror had to know beyond a reasonable doubt that Anthony committed this crime and by finding her guilty, be potentially willing to sentence her to death.

It might be easy to say you would do things differently but when it appears you might actually have a life in your hands, you are going to evaluate each and every detail a bit more closely.

And despite its best efforts, the prosecution simply did not show enough reliable evidence during this case to convict Anthony. While it certainly painted a murky picture when evidence showed someone on Anthony's computer looked up chloroform, there was no way of proving it was definitely Casey Anthony that searched that.

Furthermore while the science of determining a rotten body based on smell might become a thing of the future, right now that science is simply too unproven and unreliable.

Nowhere during the case did the jurors find out the date of death for Caylee Anthony, the time of death, or even the location of her death. In most cases those would seem to be necessary details, but most don't consider that information when determining Casey Anthony's guilt or innocence.

For some people even her tattoo Bella vita, meaning beautiful life in Italian,  proves her guilt because she got it after the disappearance of her daughter.

Was that decision a bit bizarre given the timing? Sure, but again that doesn't prove her guilt.

You can decry the fact that our justice system didn't force Casey Anthony to take the stand in her trial, but until that changes you can't complain about the decision the jury reached.

In situations like this, in which Casey Anthony is the only person in the world who knows the truth, you have to just follow the letter of the law.

And in this instance, no matter how likely you think she might be guilty; if the evidence isn't there you cannot convict the person.

No matter how much hate they will likely get, this Florida jury got it right.
