It would be wonderful if, instead of allowing the Mexican president to lecture Arizona on trying to defend herself, Lord Zer0 would pick up the phone and tell Senor Calderon that if Mexico can't control its criminal elements, he will do what is necessary to keep them contained inside of Mexico.
I do feel very sorry for the average Mexican trying to keep his or her head down and stay alive. However, we couldn't possible interfere in their domestic affairs without being accused of trying to colonize the country.
So, at least protect and defend US citizens, you dimbulb.
