. . . or a man (no chance get away with).
My take is that Casey IS a psychopath. In regards to this case she is intelligent, manipulative and has the right kind of charm to throw off an otherwise competent jury. You can compare her to someone like Karla Holmolka who while being very physically attractive sexually and outwardly is nonetheless capable of unspeakable evil.
Unfortunately this is how our society works. If Homolka and/or Anthony were fat, ugly, and distasteful to look at there is NO chance in my mind that they would get away with all their lies. But it is hard for people to accept these contradictions....
