I don’t know about a thread where you gave a link to an actual scenario. But this actually happens with a fair degree of regularity.
The reason why I am asking this is to provide a little variety on the “moral theology” forum and to discuss an actual application of moral theology in the world. (Face it, this topic is a little bit different than the usual “IS IT A MORTAL SIN IF I ____(fill in the blank)_____” thread that predominates on this forum.
While the question about whether this being a crime or not is being answered with a clear majority of respondents, the question about if prison protects society from the perpetrator in this case is largely going unanswered. That is actually (IMHO) the more interesting topic here.
