Still, I would oppose the law (as does Jeb Bush, Marco Rubio, Mike Huckabee, and Karl Rove, among others) on the grounds that it potentially changes for the worse the relationship between the community and the local and state police and risks treating some people as guilty until proven innocent. The Arizona law, in my estimation, nudges things a bit in that direction, which concerns me.
The article is well reasoned and clearly written while not being too wild on either side. It also contains links to a debate by two journalists, Michael Gerson of The Washington Post and Byron York of the Washington Examiner.
Ultimately, as someone who sees free (or relatively-free) immigration as compatible not only with Catholicism, but also conservativism and capitalistic-economics, this law is wrong, in my opinion. And more importantly, the law also seems to pertain of future, even more-drastic legislative decisions.
