The judicial system is flawed and the Manson case points it out real well.

They convicted all the members of the manson family that were involved in the muders saying they were crazed killers and knew what they were doing. They all went to jail and are probably still there today.

Then they convict Manson saying he brainwashed the people under his control and made them commit the murders. You can't have it both ways. Either manson brainwashed his people to commit the murders or those people knew damn well what they were doing and Manson is innocent of the actual murders. He was only guilty of the conspiracy to commit the murders.
