Pure Bull, Mr. Chapman.
I don't know where you get that idea of harsh enforcement (that's a fantasy, Sir), and that harsh border security(. Borders are as porous as a they have ever been. DO SOME RESEARCH,. I know you wont because you Liberal fools never do, just spout LaLaLand nonsense.
That was and IS the problem!
When we had CIR (Amnesty) in 1986, it was promised to be the last time. Borders were to be secured, visa tracking system in place (THAT was supposed to have been done, by LAW, 1990, here it is 2012 and STILL no visa tracking!) and enforcement stepped up.
There's STILL money for the fence being spent for everything but a fence.
Now YOU stupid dolts want to play that silly game, AGAIN?
