You often hear the pro amnesty advocates' talking point: "Our immigration system is broken -- it needs to be fixed." But few Americans ask why it is broken. The answer is simple: Our immigration system is broken because our immigration laws aren't enforced. No reform can fix the "broken system" unless our immigration laws are enforced -- and no reform is needed if we enforce our existing laws. San Francisco's district attorney, Kamala Harris, who is seeking to become California’s attorney general, epitomizes the reason our immigration system is broken.
