Forget the Bible - amnesty is a good way to get past the fact that undocumented illegals are living below the radar with no fix in sight. You going to pay to round them all up and ship them out? Not by yourself, so before you start a spending spree with MY tax revenue - think of a plan beyond the knee-jerk that you know is not, nor has it ever, worked.
The Bible says that people should follow the law. What part of illegal don't people understand? If you made the choice to commit a crime, you deserve to pay the consequences for it. It's just not fair to grant amnesty to people in this country when there are millions(especially in Europe since liberals like Ted Kennedy basically stopped white immigration in 1965 to create a permanent liberal demographic) of people who want to come to the US but have to wait for decades. Truth is that if these illegal immigrants really want to become citizens, they could go back to their home country for 10 years and do it the right way.
