The U.S changed since the ending of slavery. Slavery was a horror in American History and something that we African Americans take seriously but it also applies to many black and white Americans as well.
Since the ending of the Civil War from 1861 to 1865 which lasted 4 years, black Americans were protected with the 14th amendment but were not equally given equal rights. This was a main issue for blacks and whites and Congress men at that time because they did not know what to do in order for everyone to agree on one specific thing. The Declaration of independence that said "All men are equal" wad a big main topic for Congress leaders and for black people because the founding fathers did not include blacks people in it.
Going down to history the Jim Crow laws and segregation was a big nightmare for black people. Jim Crow law was a law that separated blacks and whites still given "equality" to both sides but not really, because it meant that blacks and whites could not go to public places together and were divided which lead to segregation which impacted many blacks people such as MLK, Rosa Parks, Malcolm X and many to fight for freedom, equality, and justice for all.
Segregation ended finally and black people were happy but whites were not. Many riots where happening in the South and some in the North but that did not stop African Americans from doing more changes that would change American History for ever.
So that is how U.S changed.
*didn't want to go down into details to much so I just said the ones that I knew*
George Creel headed the Committee on Public Information
during the time the U.S. joined the First World War. They used every method
within their disposal to convince Americans to support the war effort. They used printing posters, radio programs
and even the movies to convince public opinion that it was necessary for
America to take part in the war.
William Wilberforce was inspired by his Christian faith to do humanitarian reforms and was a proponent for the abolition of the slave trade. With the help of some Christian, and politically involved friends they were able to push the Slave Trade Act. He also made some social reforms on working conditions.
<span>Mary Wollstonecraft was also an author of several civil rights writings and was very much of a feminist and an advocate for women's rights.

Both of them fought for the rights of people. They only differ in their focus.
Due process and equal protection under the law-- due process requires laws be carried out fairly and equally.
The laws of the US are suppose to be "blind" in particular for the justice system. Despite the sex, race, or origin of a person laws should be executed and judged equally. Despite the expectation the system does fall short because it relies on the unbiased thinking of the citizen which is difficult to come by. As a result the whole corrections system deals with the issues like the example in the question where race, ethnicity, sex, and social class can determine the outcome of arrests and ruling on laws.
