It is one thing to institute a DPS “surge” on the border; it is quite another to send the National Guard there, a thousand strong, as Perry intends to do. What is the purpose of sending the Guard to the border? The National Guard is a military force. Is its mission military or humanitarian? Who is the giving the orders? What are the rules of engagement? Who is the enemy? Are the troops going to cross the border and invade a foreign country, as Pancho Villa did in Columbus, New Mexico, during the Mexican Revolution? Meanwhile, what happens to the refugees? And, by the way, what is this going to cost? These are good questions in search of answers.
