Casey anthony not guilty?

Ive been recovering from surgery and i PERSONALLY knew this woman(choose to believe me or not either way idc) I found out that she was found not guilty recently and tbh it makes me sick..... i have socialized with her on a couple of occions(my father would invite her to family events)...... and i always felt something was.......off about her...... im just gonna get to the point.... How could the american judicial system fail like that!?! it puts me in a rage just thinking about it! when i heard that her child was missing i knew I KNEW THAT SHE HAD SOMETHING TO DO WITH IT!!!!
