Well, I'm not only talking about getting sued--there's also the issue of injury/disability--but getting sued really sucks, too. The question involves either factor, I guess--injuries or litigtion--influencing how, or whether, to act.

The scenario goes the other way, too. There was that case a couple years back where a woman in a car accident sued when she was allegedly pulled out of the wreck unnecessarily by a Good Samaritan. She ended up permanently paralyzed and she claims that she wouldn't be paralyzed if the Good Samaritan hadn't done that.
