Not necessarily. I don't think it has been indicated one way or another if this person did indeed rape a child. Other people have suggested that it was cartel related. In which case, it might not be the community, it may have been drug, gang, etc. related. This man may have not committed any crime. Usually one doesn't get stabbed by 30 knives without doing something pretty bad, but who knows.

I think the larger issue is one's stance regarding if this type of justice, provided we assume he was a child rapist for example, is one we endorse, frown upon, or simply recognize as another cultures way of handling things. Certainly everything is circumstantial, as it is with the American justice system. We have and continue to sentence individuals to death for the worst of crimes we do not tolerate as a society. Sometimes it's not the penalty that people take issue with, it's the method in which it is exercised.

Ethics, morals, revenge, forgiveness, religion, economics, politics, knowledge and/or ignorance plus a host of other beliefs dictate an individuals stance on the matter. And as Richterer pointed out, there are going to be valid points on both side of the table. When we start arguing deeply engrained ideals like these, it is often tough to come up with compromise that is satisfactory.
