This sets a very bad precedent, and it's almost sure not to survive an appeal.
Before the verdict came down on Tuesday, TV5 spoke to a mid-Michigan attorney about what a guilty verdict could mean for legal precedent moving forward
“Could a prosecutor arguably say a husband is responsible for the criminal acts of his wife? Or is a wife responsible for the criminal acts of a husband when they knew or should’ve known that they were going to be committing these acts? It’s somewhat of a slippery slope concern that I have when you start opening up more ways to hold individuals accountable for the acts of a particular person. Because traditionally in this country, only the person who commits the wrongful act is the one that gets criminally prosecuted,” said attorney Philip Ellison. <source>
Stephen J Morse, a professor of law and psychiatry at the University of Pennsylvania, said he disagreed with the verdict, arguing that because Ethan Crumbley had pleaded guilty, he was the only one responsible for the shooting.
"I understand that she was not necessarily the best mother in the world, but this is not a crime," he said.
Mr Morse said he believed the decision could set a bad precedent, causing courts to look for "scapegoats" in similar situations. <source>
