We’re not in Kansas anymore, muthafuckas
The first one was, at worst, manslaughter. The second was premeditated, but at the insistence and manipulation of one of Oz’s super powers, so she could probably get a plea deal if she’s willing to dish on Glinda.
The official term is involuntary manslaughter, but it would only be applicable to the Witch of the West, however it would require recklessness or negligence, neither of which were present. Then again, when Dorothy’s house falls on the Witch of the East, although it’s basically a death from natural disaster, she proceeds to steal a family heirloom, the ruby slippers, from the deceased witch and refuses to give them back to her kin, the Witch of the West, so there’s some degree of instigation. That does not excuse how Dorothy is kidnapped and detained, plus there’s the criminal intent the witch has to kill Dorothy. It’s a shit show all around, but that’s Kansas for you.
I remember Ted Lasso very differently
