An insecure fence?

Yesterday, President Bush signed a law committing our government to build about 700 miles of fence along the border with Mexico. Doubts have been raised as to (a) whether fencing of this magnitude will actually be built and (b) even if it is, whether it will substantially reduce the flow of illegal immigrants. The very name of the legislation, “The Secure Fence Act,” suggests to me a certain insecurity about the fence.
In the event that the fence legislation fails to accomplish its purpose, plans to provide current illegals with a path to citizenship should be taken off the table. Only after we have secured our border should we even consider legalizing illegal immigrants.
