Who would they call???
And why do Mexicans drive American HumVees???
Either foreign aid or their army bought them.
Because we provide with hundreds of millions of dollars in millitary aid.
If I remember correctly the national guard falls under the governors command and this looks like a blatant incursion onto our texas soil by a foreign aggressor violating our soverignty and laws. The pharmacist needs to cowboy up and send some of texas's finest to the border.
If I were in charge they would be calling the military. But given that they report to a President who does not care to defend our borders perhaps the could call the media.
