Arizona Immigrant ID Law Ignores Constitutional Protections

The governor of Arizona has signed into law a measure that would allow police to demand proof of legal residency in cases where they believe an individual might be an undocumented immigrant. The same law would also require people to carry proof of legal residency. It is unclear how the law would be enforced without racial profiling and whether or not US citizens would be subject to legal penalties if caught not carrying proof of citizenship.
