I vote for the jail option for the dj's.....
And 7 digits are not enough if the radio station is still on the air. The dj's were representatives of the station owners......
If you were to poll 100 people about the dangers of drinking too much water, a good percentage of them (just a guess...at least 10%, all of whom post at DU) wouldn't know that too much water can kill you. If you replaced the water with gasoline, 100 out of 100 people would know that's a risky proposition, and none would participate.
The radio station had to know that there were risks involved, and should have had all participants sign a waiver, stating in bold print: CONTESTANTS HEREBY ACKNOWLEDGE THAT TOO MUCH WATER CAN CAUSE PERMANENT INJURY, UP TO AND INCLUDING DEATH! PARTICIPANTS ACCEPT ANY AND ALL LIABILITY FOR THEIR OWN ACTIONS.
To me, this is no different than an Irish bar having a whiskey drinking contest on St. Patties day. If somebody dies from alcohol poisoning, the bar is liable.
