In 1986, Congress granted "amnesty" to three million illegal aliens, thus allowing them the legal right to remain in the United States and eventually apply for citizenship. Supporters of the amnesty promised that it would be a one-time "humanitarian" gesture. The promise wasn't kept. Since 1986, lawmakers have granted a succession of de facto amnesties to illegal aliens under one pretext or another. Pressure for more amnesties shows no sign of decreasing.    In Amnesty for Illegal Aliens — Repealing the Rule of Law, John Vinson traces the history of amnesty and examines how it is a flawed concept in relation to illegal immigration. He maintains that amnesty undermines America, as a nation under law, by rewarding law breaking. This report documents the failure of amnesty to stem illegal immigration and why the proposal to give "guest worker" status to illegal aliens is likely to terminate in amnesty.
