because the number of illegal immigrants in our population doesn't really go up, it just fluctuates. like, twenty years ago there were twice as many illegals here, but over the years its gone down, and just fluctuates.
i always thought a wall or good fence was a good idea, but now i'm not so sure.
(it's obvious a wall would keep some illegals out. if you hinder their access, less will come. it's idiotic of liberals to say a wall wouldn't prevent anyone from coming, just like it's idiotic of conservatives to say gun control or limiting guns wouldn't decrease murders. it's the same stupid idea, as if a fire extinguisher wouldn't lessen the extent of fires)
