A majority of Americans rejected the Casey Anthony verdict, which declared Anthony innocent, a new USA Today/Gallup Poll indicated.

Anthony was acquitted last week of charges that she had murdered her two-year-old daughter Caylee, the culmination of a riveting and closely watched trial. Protestors gathered outside the courthouse after the verdict was handed down, and the Anthony family has reportedly endured death threats.

The reaction in part reflects the dissatisfaction of thousands of people who closely watched the trial, in some cases becoming emotionally invested, only to be left without any answers for how Caylee died.

It's frustrating that they can't come up for a definitive reason for this girl dying, Sherri Cohen, a self-employed photographer from Fort Lauderdale, Fla told The Associated Press. Archaeologists can tell you about bones that were found thousands of years ago, but they can't tell you how a 3-year-old girl died three years ago.

Prompted by a similar instinct, lawmakers in Florida have been pushing for Caylee's law, which would make it a felony to not report a child's death or disappearance.

I was shocked to find out it's not against the law to fail to report a missing child, said Rep. Clay Ingram, R-Pensacola. Right now, with all the media attention on the trial, I think this is a good time to introduce this.
