Are involuntary manslaughter cases not usually predicated on some sort of negligence or other criminal activity on the part of the manslaughter? I don't think I've ever heard of anyone being punished for being the person in the wrong place when someone else decides to commit suicide by train or vehicle, for example. If we take the comparison down a step (and into what I think is maybe a more comparable situation), I routinely see warnings in parking lots that they are not liable for stolen property or damage and imagine those are generally probably pretty accurate outside of, again, some negligence on the side of the business.
