Armin Meiwes was a man who met another man through the internet. The two agreed to meet. So far so good. However, the terms of their engagement was such that Meiwes would kill and eat the other man. All voluntarily.
In all seriousness, however, this man is now unfortunately imprisoned for life for partaking in a consensual act with another adult. Is this an injustice or merely a sound hearing on the (implicit) rules we have all agreed to play by?
