An estimated 60,000 took to the streets of Los Angeles Saturday for the cityâ€™s leg of the national Reform Immigration Union 2010 marches, waving red, white and blue flags.
The protest was part of the international â€œMay Dayâ€ demonstrations held worldwide, from Athens to McCau.
May Day is synonymous with several public holidays including International Workers Day, also known as Labour Day in parts of the world.
In Southern California, the march was in response to the recently passed Arizona bill, SB1070. Los Angeles was one of over 70 cities in the United States voicing opposition to the bill.
The recently passed legislation will be the most rigid anti-immigration law currently active in the United States when it goes into effect this summer.
By signing the bill, Gov. Jan Brewer brought Arizona to the forefront of the controversial issue, drawing considerable criticism nationwide including civil liberty and racial profiling concerns among human rights groups.
Among other measures, SB10170 allows police to check citizenship status based on suspicion alone. Arizona lawmakers claim it is aimed at counteracting the violence of Mexican drug cartels.
Emotions flared on both sides of the issue with signs and banners displaying both messages of equality and intolerance.
The protesters, calling for repeal of the their neighbor stateâ€™s legislation and federal immigration reform, were addressed by the likes of pop star Gloria Estefan, Cardinal Roger Mahony and Los Angeles Mayor Antonio Villaraigosa, who has publicly boycotted Arizona.
