A couple of the comments at this religious blog are of interest:

Clearly, the Scriptural message calls for some degree of humane provision for foreigners. And so many of the people you encounter are hard working people trying to get money back to their struggling families in their homelands.

But, I don't see a "carte blanche" mandated in Scripture, either. Having lived in SoCal almost all my life, I have watched the exacerbation of crime (especially gang violence) thru Mexican and Central American gangs. Also, communities all over the region are losing their medical trauma centers because immigrants see these as free primary care centers and simply break them financially...

(His link). And:

If you find a person who you know or reasonably suspect to be a criminal, should you help them if they are in need of food or medical attention? They Christian answer is yes. There is much in Holy Scripture which supports this position.

Having filled emergency needs of a criminal should you help them in their criminal activity or help them evade law enforcement? I find no scripture which supports a yes to this question. I find scripture which says we should answer no...

The spin here is the claim that it would make it a crime to help an illegal entrant by providing food, water, or medical attention. That is not the case, what is the case is that after giving such aid law enforcement should be contacted. This is not different than the requirement in many communities that hospitals report all gun shot wound. The desire is to defeat legislation which would make it clearly a crime to help illegal entrants to continue in their illegal entry.

What would be really interesting would be for pro-American religious leaders to publicly oppose Cardinal Roger Mahoney's corrupt, immoral stance.

(I put a nofollowtag on that link not just for the normal reasons but because I left a comment there and it never showed up. Despite that, I think the comments are too helpful not to note.)
