There is a story on Fox News WEB site which references various government documents to make the case that most of the weapons used by Mexican Cartels come from various U.S. Government sources. They point to weapons sold to the Mexican government, stock piles in Central America and sales to Latin American governments. I thought it was an interesting read.
A major source of objection to a free economy is precisely that it ... gives people what they want instead of what a particular group thinks they ought to want. Underlying most arguments against the free market is a lack of belief in freedom itself.
