I just want to clear a few things up because I live in this area, fairly close to the radio station that hosted this.
First things first, they didn't sue the radio DJ. They sued the highest corporation who had nothing to do with the contest and probably weren't even contacted until it was too late. It's like if MTV held a similar contest and then someone sued Viacom. When radio shows have contests, typically the highest part of the corporation only gets involved when the prize is something like a vacation, or something expensive. But a Wii is a Wii. You don't need to sign a contract, they aren't that expensive (usually they only get involved with prizes above $1000). And the contest wasn't all that complicated. It was stupid sure but nothing that requires corporation consent. Which leads ME to believe that this wasn't a justice thing. If it was a justice thing, the family would've sued the DJ with criminal charges. Instead they file a suit against the corporation for a hefty fine. That isn't suspect at all. No ulterior motives here.
Secondly, even if you don't know about water poisoning, which I didn't, anyone who knows anything about how the human body works, meaning they know where pee comes from, will know that drinking a lot of liquid and then just holding your bladder is harmful. Water poisoning isn't the only thing that can happen when you drink too much water. Really, drinking too much water in a single sitting is the same as drowning. Drowning isn't completely suffocation. A lot of it is just the intake of water. And I imagine the DJ DID have waivers because if he didn't, then that's another stupid thing. I would never participate in a contest without a waiver. Yes I know waivers are to save the companies ass usually but it also indicates some responsibility that at least they recogonize that something could happen. I had to sign a waiver for a screaming contest, a SCREAMING CONTEST. Because apparently there's a very slim chance that I could damage my vocal cords to the point of voice loss or something. But I believe they did have waivers but juries don't care about waivers when someone dies. Especially when its so easy to paint that person as a victim.
Lastly, I have to bring up the fine again. Everyone's saying "Oh its a poor mother of three" and that money will not bring her back. Your right. So why is the family suing? If they were charging the DJ, I'd understand. If they were seeking criminal prosecution, I'd understand. They want justice. Whether or not it was the mothers fault or not, that isn't as much an issue when they're seeking appropriate charges. But no, they went to the highest they could and sued for a fine. No one finds that suspicious? No one thinks it's the least bit strange that instead of knowing that the DJ responsible for the irresponsibility is in jail for his actions they go for the money? Personally, I think that the husband has a little greed up his sleeve and I think part of it is because we live in an advantageous society. If you see an opportunity for material gain, you take it, no matter how despicable. Sending the DJ to jail, oh whatever, I don't get anything I can hold and feel good about. Lets get money instead.
Really, I don't think this is as much an issue of the mothers stupidity, and it was stupid, but really many other people participated as well and certainly people would participate again even after this. Its more about the family, most particularly the husband I believe.
