I think, and hope, you're right. But as I understand it, the burden goes something like this: "Is it more likely than not that Kyle wrongly caused their deaths?" I don't know how wrongly is defined in WI civil statute, and I don't care enough to look it up. I am heartened that nothing's been filed yet. I think the longer the plaintiffs wait, the more of an indication it is that their case is weaker than they'd like it to be.
I can see Rosenbaum going the other way, given the wrong jury. But, again, I'm not as knowledgeable about the ins and outs of the case as the lawyers will be by the time this goes to trial.
