Answer: He mentions police brutality and lack of voting rights.
Explanation: To understand how police forces in the USA have long been able to perpetuate a resistance to the expansion of personal liberty for minorities, we should inspect the federalist roots of our government. The USA took little interest in protecting African-American rights until the Civil War. In the Reconstruction-era legislation, Congress planted the seeds of federal protection that would lie dormant for decades until the Franklin Roosevelt administration determined to cultivate them after all.
Yet, police brutality persisted , sparking riots in desperately impoverished communities throughout the 1970s and 1980s.
As regards voting rights, prior to the passage of the Voting Rights Act in 1965, African-Americans and many others faced regular and malicious restrictions to the free excercise of their constitutionally protected right to vote, specially in the South.
In a 1957 speech titled "Give Us the Ballot", Dr. King spoke plainly about the imperative of equal voting rights. For King, the right to vote was sacrosanct and foundational. It is the very essence of our social contract.
