I thought the Temecula CBP were very 'specifically' conducting round ups. Terrified the illegal community.... keep it up and a lot of them will stay home.
Don't have to do much more than that and you will realize a big difference.
You might be right, other than the fact that you're wrong. Send 'em across the border, they come right back. If the worst thing that happens to you is that you have to go back, you take the chance that you won't be the one caught.
When I was growing up all you had to do was to yell "Immigracion" in a restaurant and the place would clear out. Now if you yell "immigacion," an illegal alien host will calmly walk up to you and ask you in Spanish where you want to sit.
