People in general still think women aren't capable of committing such horrible crimes. But when they do I think the justice system still goes easier on them, especially if they're young, white, and physically attractive. (They usually look unattractive to me, either because I'm also a women, or because even though I'm not supposed to be good at reading facial expressions, I can see the ugliness of their thoughts showing on their face.
And that is sexist and completely wrong.
After all the media sensationalism over female murderers and child molesters in the US, I have decided to humanely put down the terminally ill creature that was my faith in humanity, and avoid the media that made it sick in the first place.
