The police records from the SNSP are missing 1,153 murders in Chihuahua! I am not able to rightly apprehend the kind of confusion that would provoke such a discrepancy. Just to give you some perspective, in Ciudad Juarez, Chihuahua's biggest city, there were 1,653 homicides, more than the 1,414 reported in the whole state according to police records. How can it be that there was such a big difference?
