If we enact a law that makes clear we're going to dramatically increase enforcement without allowing greater legal flows, employers and illegal immigrants will find ways around it.

The Family Law Act, which was the child of the disgraceful Senator Lionel Murphy, should be repealed. It has brought death, misery and heartache to countless thousands of Australians. Children are treated like pawns in some crazy game of chess.

I don't understand why a law enforcement agency that has abandoned the use of the application of chemical agents on nonviolent protesters for seven years needs to litigate this issue in pursuit of a judgment that will essentially void the jury's decision and give local law enforcement agencies free rein to use pepper spray when none is needed in light of the 100 percent success rates since abandoning the use of pepper spray.

But it gives the law a little more bite.

Going in, economists thought that once trade barriers were lifted that small countries would benefit. But we found that cost barriers exist that only large countries and large corporations can overcome.

You're trying to legislate and end immigration in the face of tremendous economic demand for illegal immigrants. Just like with the illegal drug trade, we can say it's illegal, but that doesn't mean it's not going to happen.
