Not just at the border. Foreign invaders found anywhere in the country should be executed and their minor children shipped home to relatives or orphanages.
From that perspective, Mexico has declared war on the USA. Their citizens are invading and are not in uniform and are therefor not protected by the Geneva Convention. Ergo, they are spies and can be shot when discovered.
Public hangings would cause them to self-deport at zero cost.
I've been saying this for years. Put a $1000 bounty on any and all illegals brought in for deportation, with a $5000 penalty for making a mistake. Then put the illegal on a chain gang at hard labor for a few months before deportation. Bill the employer if the illegal worked anywhere and the employer failed to check his legal status. This seems like a very moderate position to me. Lately, I've been leaning toward Neal37's solution, except with very public executions of anyone found in the country illegally. A death penalty -- actually carried out and not some silly death row forever -- would be a valuable deterrent. I can almost hear the whooshing sound of 30 million illegals rushing back to their own country.
