'They offered an opinion, NOT medical advice'
A nurse called in and told the DJ's that what they were doing was not dssafe and can kill them. The DJ blew it off and stated as if he was absolutely sure that this could not kill her.
The onus was on them to guarantee a modicum of safety to their contestants. Just like I assume my employer performs regular maintenance on my work truck there's a degree of assumption a person makes every day concerning possible fatal things which are completely reasonable.
An anonymous, disembodied voice on a phone line is meaningless. Those DJs have no way of verifying whether that voice belonged to a real nurse or not. When we have the anonimity of the telephone . . . . or the Internet . . . . any of us can assume any persona that we wish. That's why you are Bogey780 and I am DustyMoment and not Ralph and Ashley. We can assume whatever identities we choose - but it doesn't make either of us experts in the fields we claim.
