Do you think casey anthony is guilty or innocent?

ive been following this case since nancy geace picked it up back in 2008, and im still undecided. When i hear the evidence i believe without a doubt that she's guilty, but when i see her sitting there in court, something makes me believe that she might not have done it. Whats your opinion? Do you think she killed caylee or do you think it was really an accidental drowning? what penalty do you think she will receive if she is ruled guilty?
