i have read SB1070 and i know it does not state that; no law does. that is the point.
it is rather the hidden potential of a lawand its application by law enforcement that is subject to scrutiny. while the law stipulates that the primary reason for detaining an individual cannot be to ask for proof of citizenship and that there must be an aura of su ion it also does not indicate anything regarding the rights of groups or persons as the enforcement of the law is applied.
that is why both MALDEF and the ACLU in the first lawsuit that was filed in the state stated the the law " invites racial profiling against people of color by law enforcement in violation of the equal protection guarantee and prohibition on unreasonable seizures under the 14th and Fourth Amendments; and infringes on the free speech rights of day laborers and others in Arizona."
