Kevin, please correct me if I am wrong.
It was a case of where a person died, true.
It was not premetitated for a person dieing.
Now it comes to the attention of the Station DJ's being called and telling them they could cause damage which they ignored as a waiver was signed.
Now, where is the culpability for a true crime? Stupidity?

Yes!
Would it possibilty of a misdomeaner or a felony?
Just a guess, misdomeaner and being stupid. Of course they have been fired but what justice should be meted out?
