Like the Brady's and many others that have tragedy like these, they turn it into a second career. I am not saying it is solely for money, but that does ultimately play a larrge role in it. The passion from the tragedy gets turned into a cause celeb, which turns into a lobbying group which takes in money and funds lots of salaries for people. The Brady family has used it as a source of income for many years.
Just like Al Gore with green energy, only he's made his cause a veritable gold mine.
