Show me where they used actual FORCE and I will agree with you, otherwise you're just projecting.
You don't have to grab a bottle of something and force it down someone's throat to be culpable if they die because of it. If you set the situation up, encourage them to do it despite knowing the risks, tell them things about it that are misleading, and blow off people who warn you about the danger you are putting these people in, you don't have a leg to stand on either morally or legally. These radio station people are going to find out a lot about personal responsibility in the coming months -- and they'll find that theirs is a hard thing to duck.
