So what would count as murder that was not premeditated, as opposed to manslaughter then?
I thought premeditated required the person to have reasonably thought about what they were doing.
If it was a violent argument where he started waving a gun around, and shot in the heat of the moment without really thinking about what he was doing, would that really pass as being premeditated in a court of law?
if she's hiding in a toilet and he picks up a gun, walks in and shoots through a door then I would say yes, its premeditated. If he has a gun in his hand and shoots on impulse while she's standing in front of him, its murder. It is the act of walking from one place to another to commit the crime that makes it premeditated.
