"Mexican drug lords exist to feed the US drug market. And they get their guns through the US weapons market. We give the bad guys their money by buying their drugs; we sell them the guns that enable their continued existence; and they threaten a nation of more than 100 million people at our border. What's the solution? According to writer Jacob Bronsther, it's two-fold: As to the guns, there aren’t any magic policy bullets, but closing down the gun shops arrayed at the border, possibly though zoning laws, is a good start. The 2nd Amendment doesn’t cover Mexican drug lords, gladly. We should also increase the penalties for smuggling weapons."
