Thanx Jece, well I have to make some precisions.
1. Around here Mich stands for Michoacán (which is a very beautiful state, where my mom once lived, so I feel more specially attached to it than to the other places I've mentioned), sorry for the confusion.
2. Krellin, as of this moment the link of the image is working again.
3. Ostula is a far town, and after the conflict with the army, the people there closed the entrance to strangers. It provoked a big deal of confusion, and Ostula people had earlier sent a communication in in which there had been more deads than there really were. Seems that the other children and the 60 y.o. were very hurt, and probably they thought they were dying. But later seems there was another communication correcting this point.
4. So it seems (and still it's not very clear to me) that we have only 1 child dead. Still we have to face the fact that the army shot against children killing one and hurting badly another 2 (plus other people, whose exact number I don't know).
5. Steephie, your idea is certainly good. I have to say that as of 2006, the army was not so used within the country, but the there was the Calderon presidential decree to allow it, because of the 'narco war'. (Up to now, that 'narco war' has proved absolutely useless, but has allowed this kind of army crimes).
