Is Is Illegal Immigration A Bad Thing?
I'm getting mixed signals, here.

First, here's some of an article from the USCCB's version of Pravda; (Emphasis mine) Cardinals say immigration at 'dark moment' in US but call for hope

WASHINGTON (CNS) -- Two Catholic cardinals called the current U.S. immigration situation "a terrible crisis" and "a dark moment in our nation's history" in remarks they made July 28 at the opening Mass and plenary session of the 2008 National Migration Conference.

Both Cardinal Theodore E. McCarrick, retired archbishop of Washington, and Cardinal Roger M. Mahony of Los Angeles urged participants to hold on to hope in their work with immigrants for local and national church agencies.

Much of the agenda, built around the theme "Renewing Hope, Seeking Justice," reflected the struggles faced by those who work with immigrants.

Workshops were scheduled on topics such as "How to respond to federal raids," "Identifying and supporting survivors of traumatic events," (anything like the 'traumatic event' posted below?) "A Catholic response to human trafficking" and "Parenting challenges from an African immigrant perspective."

Another two dozen workshop sessions dealt with legal issues including "Filing waivers of inadmissibility" and "Immigration law and crimes"; strategies for fundraising; and getting out the church's message on immigration* (here's the REAL Church Teaching).And then we have this from some of the piece done on Spero News; (Emphasis mine) Protecting illegal aliens at US citizens' expense

Members of the Mara Salvatrucha criminal gang allegedly murdered a San Francisco father and two sons. The perps benefited from San Francisco's liberal attitude towards illegal migrants.

It was a Sunday afternoon last June and Anthony Bologna and his sons Michael and Matthew were almost home from their family picnic. Anthony, driving the family car, briefly blocked another car from completing a left turn down a narrow San Francisco street. Angered by this momentary delay in his trip, according to police reports, Edwin Ramos got out of the car and opened fire on the Bologna’s car with an AK-47, shooting all three men. Tony Bologna, 48, and his son Michael, 20, died at the scene, and Matthew, 16, died a few days later in the hospital.

Police arrested Ramos a short time later, believing he was the gunman, although two other men were seen in the car with him. Ramos is an El Salvador native and a reputed member of the notorious gang known as MS-13, one of hundreds or thousands of illegal aliens in San Francisco who have benefited from the city's long-standing practice of protecting illegal immigrant juveniles who have committed felonies from possible deportation, according to The San Francisco Chronicle.

Now charged with three murders, the 21 year-old Ramos was previously found guilty of two felonies as a juvenile: attempting to rob a pregnant woman, and as part of a gang-related assault on a city bus passenger. By all accounts, Ramos is a vicious animal who has no business being in the United States, and no business being in San Francisco.
Officials with the city's Juvenile Probation Department failed to alert federal immigration authorities following both of the felony convictions because it was the agency's policy not to consider immigration status when deciding how to deal with an offender. Had city officials investigated, they would have found that Ramos lacked legal status to remain in the United States, and should be deported. Three members of the Bologna family would likely be alive today if that had happened.But why pay attention to the law, either Church or secular? Our own leaders don't.

In the meantime, real American heroes, Ignacio Ramos and Jose Compean, remain in solitary confinement for protecting our country.

*2241 The more prosperous nations are obliged, to the extent they are able, to welcome the foreigner in search of the security and the means of livelihood which he cannot find in his country of origin. Public authorities should see to it that the natural right is respected that places a guest under the protection of those who receive him.

Political authorities, for the sake of the common good for which they are responsible, may make the exercise of the right to immigrate subject to various juridical conditions, especially with regard to the immigrants' duties toward their country of adoption. Immigrants are obliged to respect with gratitude the material and spiritual heritage of the country that receives them, to obey its laws and to assist in carrying civic burdens.
