At present, Article 67 of Mexico's Population Law says, "Authorities, whether federal, state or municipal ... are required to demand that foreigners prove their legal presence in the country, before attending to any issues."
Seems Arizona is actually requiring less with it's new law. Yes, they intend to deport illegals, but will still attend to issues such as needed medical help.
So all those protesters (mostly misguided Mexicans, aging hippies and mush-brained college puppets) should be protesting Mexico's laws... they're tougher than Arizona's, and a lot less humane.
Consider: Mexico is not mistreating Mexican illegals, they are mistreating South American illegals passing through Mexico trying to get here.
These protesters waving all those Spanish signs and Mexican flags that do not like our immigration laws most likely realize that, so it looks like a huge double standard to me.
They are protesting Arizona's right to conduct proper and legal treatment of criminals. Yes, they are criminals. By crossing our borders illegally, they break the law. That's what we all call lawbreakers... Criminals.
They are the real racists here. They don't give a damn about Mexico's mistreatment of Bolivians, Costa Ricans and the like, just Arizona's supposed mistreatment of their cousins.
Just ignore them. They are clueless when it comes to right and wrong.
