Rick Perry supports aerial Surveillance of the border.
I think there may be a hitch with using 20mm tank cannons on folks though, unless we declare open war with Mexico.

OK, skip the A10 gatling gun idea. How about Predators with Hellfires? They seem to be effective elsewhere. Maybe we can have the same command posts controlling the ones in Yemen as well as the ones on the border.
