What b.s. He's politically grandstanding, nothing more. He can threaten anything he wants. There is a huge, huge, huge difference between saying consciously doing something you know will cause a substantial risk of harm is a crime under hte law (e.g. drinking lots of alcohol and driving) v. co-sleeping poses a substantial risk of harm UNDER THE LAW!!!
Obviously, the case presented, a mom drunk and high, who suffocated killed her baby is a very different case.
