Final answer:
The information provided in the question refers to the historical Freedom Riders, a group of civil rights activists from 1961 who challenged segregation on interstate buses in the southern U.S. If the question is about the contemporary Bus Riders Union in Los Angeles, it is a separate advocacy group focused on improving public transportation and fighting transit racism since the 1990s.
Step-by-step explanation:
The Bus Riders Union of Los Angeles
While your question refers to the Bus Riders Union of Los Angeles, the detailed information you provided pertains to the Freedom Riders and not a Los Angeles-based group. The Freedom Riders were civil rights activists who rode interstate buses into the segregated southern United States in 1961 to challenge the non-enforcement of the United States Supreme Court decisions Morgan v. Virginia (1946) and Boyer v. Virginia (1960), which ruled that segregated public buses were unconstitutional. The Freedom Riders faced severe violence from white supremacists, particularly in Alabama and Mississippi, drawing national attention to the cause of civil rights and enforcing federal laws against segregation.
However, if you are referring to a contemporary organization known as the Bus Riders Union (BRU) in Los Angeles, which is not detailed in your question but might be conflated with the historical Freedom Riders, the BRU is a mass transit advocacy group that seeks to improve public transportation in LA and fights against transit racism. Founded in the 1990s, they are known for their legal and advocacy efforts to ensure equitable access to quality transit services irrespective of race, class, or neighborhood.
