How can they defend these people?

Watching the interview with Casey Anthony's attorney w/ Matt Lauer utterly disgusted me and made me want to hurl my oatmeal at the TV. He knows she killed her daughter, I know she killed her daughter, the WORLD knows she killed her daughter, and her parents probably know too but are in a serious state of denial. Presumption of innocence until proven guilty may be our country's judicial policy, but in the Gospel according to Michele Christine, it is utter bullshit.
