The most sensational murder trial of a two-year-old Caylee Anthony concluded Tuesday with a verdict of Casey, Caylee's mother, found 'not guilty' shook the nation. Americans across the expressed their fulsome anger in social media.

The jury in Casey Anthony murder trial took 10 hours and 40 minutes to decide that the accused did not kill 2-year-old Caylee Anthony three years ago.

In a dramatic and controversial conclusion to a legal battle that had the nation riveted, the jury pronounced that Casey Anthony was not guilty of first degree murder, aggravated child abuse and aggravated manslaughter. She was found guilty only in four counts relating to lying about the child as missing.

According to legal experts, this was a verdict very few people who watched the trial had expected. Legal analyst Dan Abrams told ABC News that the jury focused particularly on very minute points of evidence, as it often happens in high profile cases. In this case there was no physical evidence, no trace of blood and no confession.

Some have raised the question whether the Jury would have let them go if they were Black. If she were black teenage single mother, then she would have been convicted. But plenty of other whites who killed their children are also convicted.

Diane Downs was just as sensational and unsympathetic; who shot her three children, killing one, and then told police a stranger had attempted to carjack her and had shot the children. She was sentenced to life in prison.
