Where do Mexico's guns come from?

According to the main stream media and our trustworthy Attorney General, Mexico's violence problem is the sole responsibility of evil assault weapons purchased in the United States and smuggled across the border into Mexico by the drug cartels. Well here is another point of view. I know. this piece is "anecdotal", but unlike the stories in the news that have the aroma of bullshit. This has the ring of truth.

Mexico has a gun problem, just like they have a drug problem and both the U.S. and Mexican governments are trying to place the blame on U.S. gun owners. U.S. gun owners aren't the problem. Mexico is the problem. The government is corrupt from the lowest level law enforcement officer shaking down American tourists for traffic violations, to officials and politicians highly placed within the Mexican government, including elements within the military. Everyone knows it. Everyone in Mexico knows it. Every law enforcement official in the U.S. knows it, and everyone in our government knows it. And anyone who has worked for any length of time within border cities and lived in the local community knows it. This is taking a Mexican problem, blaming the U.S. by turning it into a crisis in order further an agenda, and Eric Holder and President Obama knows it and they are taking advantage of it.
