The scandal of the narco-photos reflects a deeper problem that lies at the heart of our transition to a democracy: the absolute absence of understanding for a good part of the population and the authorities of the rule of law and human rights. Ultimately the conflicts between the authorities and the criminals are only an issue of power and not legitimacy. There are no "good guys" and "bad guys" in this fight: just two bands looking to do away with the other.
Good point. This gets at why cleaning up the army shouldn't be an issue merely for AI and Human Rights Watch and knee-jerk opponents of Calderón, but first and foremost for those who favor a confrontational stance and think the army has a role to play in the fight against drug trafficking. The longer the army acts as or can be seen as a serial abuser, the harder it will be for the government to paint themselves as the legitimate party.
