Arizona's new law on illegal immigration could violate international standards that are binding in the United States, six U.N. human rights experts said Tuesday.

The basic human rights regulations, signed by the U.S. and many other nations, regard issues such as discrimination and the terms under which a person can be detained, the experts said.

"A disturbing pattern of legislative activity hostile to ethnic minorities and immigrants has been established with the adoption of an immigration law that may allow for police action targeting individuals on the basis of their perceived ethnic origin," the experts said.

1. The Arizona law doesn't go beyond federal law and is designed to be consistent with state and federal civil rights laws. Unless they're willing to explicitly say that federal immigration laws are unjust then their concerns are unfounded. Enforcement of the Arizona law will also be closely monitored by far-left supporters of massive illegal activity such as the American Civil Liberties Union.

2. The apparent ringleader is the United Nations Special Rapporteur on the human rights of migrants Jorge Bustamante. He's a Mexican citizen who teaches at Notre Dame; see his name's link for past coverage. Among many other things, he wanted Mexican immigrants to the U.S. to become U.S. citizens in order to push Mexico's agenda inside the U.S

Those joining him were:

- Special Rapporteur on contemporary forms of racism, racial discrimination, xenophobia and related intolerance Githu Muigai of Kenya;

- Special Rapporteur on the situation of human rights and fundamental freedoms of indigenous people James Anaya of the United States;

- Independent Expert in the field of cultural rights Farida Shaheed of Pakistan;

- Special Rapporteur on the right to education Vernor Munos Villalobos of Costa Rica; and

- Independent Expert on minority issues Gay McDougall of the United States.
