I will tell you one thing, you can't stop determined people. Illegals aren't going to be stopped by BPA who have guns but aren't allowed to fire them. Illegals won't be stopped by a cheap fence. If someone wants to steal a car, they can do it. If someone wants to do drugs, they can do it. You can't just stop illegal immigration, you have to curb it. The goal should be to try and reduce the illegals in this control, and deport them as necessary. Common sense rules first though, if a kid was conceived in this country with his parents and they have been living here for over a decade, I think they should be left alone. Here's a fun fact for you all:
Illegal Immigrants have killed more Americans in the past 4 years than Iraq has killed our troops.
They are NOT allowed in the country, plain and simple. I only feel pity when an innocent child gets involved.
