Can you tell they're illegals just by looking at them? I believe Az wanted them to start carrying papers and to allow Sherrif Joe to stop them. Comon, you all hate Hyspanics down there.
That's what SB1070 was all about - basically, Driving While Brown.
A national law enforcement org showed that Pima county sheriff, Clarence Dupnik was #1 in the country for actually catching and deporting illegals while Arpaio is #13. Arpaio doesn't actually do much except brag about what he'll do in the future. Just re-elect the old fart, that's all he cares about.
Not all of AZ is racist and stupid though. There are Christian groups who put out water for them and I never hesitated to help those who came to my door.
Mexicans are just like everyone else - there's good and bad and they're mostly good.
