The Times on Mexican drug killings

A story today again about the drug killings in Mexico and their effect on children says this is happening "throughout Mexico" but reports on horrible incidents in Tiajuana only (and refers to the state of Chihuahua having the most killings). Why do they do this? Why do they hate Mexico? Gosh, I live in Mexico and I can tell you it's a big big country. The crime rate at the border does not hold true in the interior, at least not in the mountains of Guanajuato. It's as if killings in Detroit were reported in a Mexican paper as indicating the violence level throughout the US. Please New York Times, give us a break!
