It is really hard to say how US citizens on the Texas border will react. There is a large number of hispanic citizens that live there. Most are very peacful once you get out ofthe big cities. Illegals will not be your biggest concern in shtf it will be the cartels that try to move in and take over that will be the biggest threat. It will take an orginized force to stop them. They will just mow over 4 or 5 guys from a community with guns and that will be about all they have to kill in that community to take control. Fear does strange things to people.
