I have to say, if those are legit cases, that is truly unfortunate. If I was on the jury, I wouldn't give a trespasser a dime, "attractive nuisance" or not.
Those are legit cases, but they don't often make it to the jury. The costs of defense force many to settle cases that they could win at trial. Add to that the fact that juries are unpredictable. A jury might say: "He's a doctor, doctors are rich, it won't hurt him to pay that poor man some money. This happens a lot to the government and businesses at trial.
