I'm watching the first series of The Good Ship Murder (I know, crap cheesy telly, but it's an easy watch!). I've watched 6 out of 8 episodes and all of them have been a woman who committed the crime(5 murders and 1 fake kidnapping & blackmail).
I'm noticing this more and more often, that women are being portrayed as murderers and violent criminals, when we know that generally this isn't the case, and men commit the vast majority of violent crime.
