Undocumented immigration down in AZ

Consider the source (I haven't checked the statistics yet, but you can here). Russell Pearce, the architect of SB1070, which is now under consideration for its constitutionality by the Supreme Court, has an editorial in Town Hall showing that undocumented immigration is down only by .1% in the US in 2010, but down 23% in Arizona during the same time. It would not be surprising if SB1070 is working to deter LOTS of people, especially immigrants and people of color. Arizona is now a very scary place to be.
