The 2010 push for amnesty for about 20 million illegal aliens will soon be in the news.

We will hear that it would somehow help the unemployment crisis. While we follow the ridiculous “we need amnesty again” arguments from the illegal immigration industry, we should remember an American hero named Robert Rosas.

Robert Rosas is a name that is sadly unfamiliar to most Americans. It shouldn’t be. His tragic story is one of many that represent the other side of the illegal immigration debate that is routinely avoided by the various anti-enforcement, open borders groups and in much of the media.

Rosas, a three-year United States Border Patrol Agent, was gunned down while on patrol on the U.S.-Mexico border near Campo, Calif., in July. He was tracking suspected illegal border crossers — future “undocumented workers” — who were headed north from Mexico looking for a better life when he was killed by multiple gunshots.

In November, Christian Daniel Castro Alvarez admitted entering the United States illegally from Mexico and killing Rosas.

Other individuals believed to be involved in the murder are reportedly still at large.

Who knows, maybe they made it into the interior of the U.S. Maybe they have been rewarded with business licenses somewhere. Maybe they have been hired by an employer trying to save a buck or two on labor expenses. Maybe they will be given a traffic ticket for a broken tail light by an American policeman and then sent on their way as the ACLU demands.

Maybe you will soon see some of them marching with other resentful illegal aliens in American streets demanding legalization, U.S. citizenship and the right to vote.

Killed at age 30, Rosas was one of more than 100 Border Patrol Agents who have died in the line of duty. He leaves behind a wife, Rosalie, a 2-year-old son, Robert, and a now 1-year-old daughter, Allysa.

Rosas’ death — and the legalization agenda — should be remembered when we consider a recent Zogby International opinion poll conducted in Mexico on American immigration policy.

As the top immigrant-sending country for both legal and illegal immigrants, views on immigration in Mexico provide insight into the impact of another amnesty, as well as other questions related to immigration.

Among the findings taken from a report on the poll from the Center for Immigration Studies in Washington D.C.:

A clear majority of people in Mexico, 56 percent, thought giving legal status to illegal aliens in the United States would make it more likely that people they know would go to the United States illegally.

As happened with the “one time” 1986 legalization scheme.

Of Mexicans with a member of their immediate household in the United States, 65 percent said a legalization program would make people they know more likely to go to America illegally. Imagine that.

More from CIS:

• Interest in going to the United States remains strong even in the recession, with 36 percent of Mexicans — 39 million people — telling Zogby they would move to the United States if they could.

• An overwhelming majority — 69 percent — of people in Mexico thought that the primary loyalty of Mexican-Americans — Mexico- and U.S.-born — should be to Mexico. Just 20 percent said it should be to the United States. The rest were unsure.

Like most Americans, Robert Rosas was sure of his loyalty. He died defending his country. His dedication to duty represents the majority pro-American side of the immigration debate.

Radical anti-enforcement, amnesty-again groups constantly howl that any enforcement aimed at illegal aliens who make it past the Border Patrol tears undocumented families apart and makes the community less safe.

They should be reminded of Robert Rosas and his American family.
