PHOENIX (AP) - Protests continue against a tough new Arizona immigration law. Thousands of demonstrators rallied Sunday outside Arizona's Capitol.
Opponents of the law say it will lead to police harassment of legal immigrants and U.S. citizens who look Hispanic.
Civil rights advocates have vowed to challenge it in court, saying it would undoubtedly lead to racial profiling. The Rev. Al Sharpton says that just as freedom riders battled segregation in the 1960s, he would organize "freedom walkers" to challenge the Arizona bill.
Supporters have dismissed concerns of racial profiling, saying the law prohibits the use of race or nationality as the sole basis for an immigration check.
Gov. Jan Brewer signed the bill into law Friday. Arizona has an estimated 460,000 illegal immigrants and is the state with the most illegal border crossings.
