I'm with SASless on this one. What happened happened, and nothing can be done to alter the event. It's now history. To be making an effort to help others understand her predicament so that they might avoid the same or similar situation is commendable.
Further to SASLess' point about what might be around the corner . . . It's absolutley true, and you won't know it when it happens. I was unlucky enough to have a 'bite you on the bum' experience - walked out with a couple of scratches, but couldn't believe it happened to me! How could this happen to me? Well it did. There is not a day goes past where I wish it didn't happen or I think about it. I hate thinking about it. I absolutely hate disclosing it.
This lady may have made a mistake or some judgemental errors, but all I see is that she is raising others' awareness to possibilities they may not think of every second and in doing so she is trying to help others. Good on her.
