It's only controversial to a jerk with a name like Jacques.
Arizona cops AND California cops routinely busted people for being in the country illegally up into the 1990s, when the La Racista mobsters started the chattering campaign about "a state cannot enforce de federal Eeem-eegration laws".
Which was a load of crap intended to defeat enforcement.
Now we need a Supreme Court decision to legitimize that which was routine for 100 years?
Well I guess the states should leave to the Feds the enforcement of all sorts of federal laws.
The States should stop enforcing drug laws, environmental laws, transportation laws.
Just think of all the federal laws that locals take care of
Obama could solve illegal immigration in two seconds. All he has to do is be reelected and they’ll all leave for better job prospects in Mexico.
