I want everybody in Texas to stop for a moment and just feel good about themselves. Breathe deeply and think of your sense of outrage and corresponding superiority. Think of your penchant for killing people. Dwell there a moment, because it won't last.
If the state of Texas is going to insist on killing a Mexican citizen while ignoring his right to contact his government for help, Texans need to prepare for something: that Mexico is going to do the same to you.
As excited as you are about another dead human being, you will be outraged that a Texan will be sentenced to life in prison without access to a Consular representative from the U.S. Embassy in Mexico. And all those feelings you have right now will be had by Mexican citizens, and the outrage will be yours.
