After spate of killings, Mexico City is criticised for failing to admit extent of crime problem | Cities | The Guardian
Mexico City has had a layer of respectability for years, but everyone knew that it was a thin layer, and that the corruption of the Cartels has sat on the shoulders and pocket books of most of the Senior Government leaders. The businesses claiming to be cartel free also had this very thin layer of respectability, but the money thrown around by the cartels is just to tempting.
But with the killing of many of the heads of the cartels and the ones in jail, the new leadership does not have the patience to play the respectability game, so the gloves are coming off, along the the layers of protection from both sides. I am not sure it is altogether a bad thing or a good thing, to end this corruption there has to be a change, and this maybe just the change needed. but everyone needs to know it will get bloodier before it gets better.
