Phoenix police officers in riot gear form a line near the Arizona Capitol after a small disturbance broke out after the signing of immigration bill SB1070 into law by Gov. Jan Brewer Friday, April 23, 2010, in Phoenix. The sweeping measure would make it a crime under state law to be in the country illegally, and would require local law enforcement to question people about their immigration status if there is reason to suspect they are in the country illegally.
