For the beginning of this story, see Touchez pas a notre prêtre! blog entry. For those who speak French, France 3 has posted a couple of videos on this marvelous story of solidarity of a parish with their priest, including an interview with Fr. Laclau. Go to http://aquitaine.france3.fr/info/30394270-fr.php.
Also, here are some photos from the protest. In the larger one below, the sign behind Fr. Laclau and the visiting priest says: "What has he done wrong except to bring us back to God?". The cardboard sign the woman is holding in the picture at the right says "Give us back our priest. Everyone with Father Leon!"
