She could have had a trial. If she had, there would have been a transcript so we could analyze the evidence and testimony from both sides. Her lawyer would have been able to challenge the charges and let the jury decide. She didn't do that. One she was placed on probation, she found out how restrictive that is. Being on paper is not fun.
Boy this is confusing. If Wisconsin has a law exempting ordinary spankings from misdemeanor assault, it sounds like she pleaded guilty to a noncrime. The judge may accept the facts... but he can't have the law dictated to him by the prosecution.
