I know, and indeed - in my country there's a special law called "Uses and Traditions" which permits the people to behave in illegal (very illegal) ways and be excused because it's a tradition.

So for instance about six months ago an entire community lynched and burned alive three cops, because they thought they were criminals.
They didn't give them a trail, even by "community" standards.
They didn't give them a chance to defend themselves... two of them died, one is still in a comma.

Even if it's "tradition" and protected by law because of that, there are some things that just shouldn't be allowed. Like raping and lynching.
