I am thinking of a better way than mowing down our southern intruders. If we did mow them down, think of the international uproar that would follow. Think of what would happen if we chased the OWS crowd out of Times Square with bullets like was done in Yemen or Syria. So therefore, the technological method which I discussed in post #544 of this thread is the best way:
If we had a robust economy the illegal population would be much more manageable. We would be able to accommodate everyone. With the economy so bad, the luxury of so many illegals has raised up to bite us. We should have had by now the ability to slow down the influx so that the accommodation process is more manageable. We should be smart enough, as the most powerful nation on earth, to create a secure border. If it requires eyes in the sky, cameras, IR sensors, vibration sensors, proximity sensors, boots on the ground and the newest satellite mounted long-wavelength infra-red sensors then we must do it. No, easily defeated electric fencing with machine gun manned watch towers is old school. We don’t even do it along the border between North and South Korea.
What do we do to them once they are apprehended? Finger print them, DNA sample them and send them back over the boarder with the warning that if they are back, we will put them in internment camps with no way to get out for a long long time. We should not spend all that money to give them a second chance. That includes families, women, children, babies—everyone caught a second time. It will be a real internment camp. We have done them before. And the message will be clear to the families that had their poor Julio go over a second time: He won’t be back and he won’t be sending money back home.
BTW, regarding what the world will think if we stop Mexicans from coming in and limiting immigration by others ~ they'll probably applaud.
Remember, the legal immigration quotas will probably never increase, and in fact, may be reduced to make up for the oversubscription to Mexicans.
