NO. fukk no.
Really, though, why do these, admittedly, brutal and ugly crimes, hangings, mass graves, beheadings, skinnings, whatever, provoke this response? Would you feel safer, if the border was closed? It's kind of a shortsighted, immature, emotional response, illogical response, 'CLOSE THE BORDERS'...why? What difference would it make? Why would you be safer with them closed? Sicarios and organized crime members aren't plotting on making it to the US to dismember us, it's a by product of the Mexican government, society, and US/world drug laws. This isn't a bloodthirsty, evil, country, it's one where because of many, many factors, a lot of blood and evil exists. It's like Canada saying this in response to the Aurorua shootings.
As far as drugs, look, in San Diego this morning, they caught 2,000 pounds of weed coming in by boat, last week, 2,500, 2 weeks before 3,500. This isn't going to stop.
