Send the drones to fly over whole sections of Dallas, San Diego, Nashville and MacArthur Park in Los Angeles to track illegal aliens, arrest, and facilitate massive deportations. They can put up a mobile Homeland Security Office on site and process one illegal after another before putting them in the vans for la frontera. Biometric their illegal, disrespectful (of US Law) asses and if they come across the border again, tabulate their costs to our LEO, sending same to the Mexican government and likewise reduce a similiar amount of US foreign aid $$$dollars$$$ to Mexico City or central American governments. They'll get the message.
Thanks. That was so sweet.
