Azetbur, I wondered that myself, but I did not see the police report, which would have come from the Milwaukee County Sheriff's Department rather than the Wauwatosa Police. I would guess that because there were no visible injuries to the nurse that could have been photographed as evidence – and no other witnesses mentioned – the DA did not feel it was worth trying prove battery, as it would have been a "her word against hers" situation. Just the amount of disturbance caused, and in a hospital no less, would be sufficient to prosecute the lesser charge. If no one else saw the alleged violence, the nurse might have to testify in a courtroom possibly filled with supporters of the accused. I suspect she would prefer not to do that. As it is, they will probably get a guilty or no-contest plea to the lesser charge, saving everyone the cost and trouble of a trial. That might not be full justice, if the accused did in fact do what the nurse says she did, but it is probably the extent of the law everyone involved can live with.
