When I first read the story in The Blaze saying that the Mexican government wants the United States to compile a registry of all firearms owned in the Southwest border states, I had to check the date to make sure it wasn't April 1st. The Mexicans believe such a registry will make it easier to track firearms found at crime scenes in Mexico.
The story originated at the website InSightCrime which track organized crime in the Americas. From their story published in January:
Mexico's Congress voted to formally ask the United States Senate to create a registry of all commercialized firearms in the states of California, Arizona, New Mexico, and Texas. Although the motion will have little impact in the US, it shows the gun control issue continues to resonate on both sides of the border.
The measure was approved January 9 by Mexico's Permanent Commission, the government body that meets when the Senate and the lower house of Congress, the Chamber of Deputies, is in recess.
The Institutional Revolutionary Party (PRI) senator who introduced the proposal said it was intended to make it easier to trace guns used in violent attacks, reports Mexican newspaper Informador.
KPHO - CBS 5 in Phoenix - followed up on this story and asked Arizonans what they thought of it. As you can well imagine, not much.

As to my opinion on the Mexican government's request, I would suggest they track the firearm diversions from their own army as well as those coming from their southern border.
