Dred Scott Vs. Stanford case was heard in Supreme court of US which issued its final ruling saying that Africans whether free or slaves were not the citizens of US.
Explanation:
Dred Scott who is a plaintiff and a slave was bought by John Emerson in Missouri. Later Emerson came along with Dred Scott to Illinois where Scott married and as they were returning to Missouri, Emerson died. Now Dred Scott decided to sue for his freedom in the federal court. He claimed he was free as he lived in the free state.
Robert Taney who was the chief justice issued the land mark decision that African american though free or slave were not the citizen of US and hence Dred Scott had no right to sue in the federal court. Dred Scott lost his case and this ruling was condemned universally as one of the racism based verdicts which paved way for the amendments of the statutes pertaining to the rights of African Americans.

Well, I believe that the cell phone has made it easier for society to give messages and helped many people dial 911 in emergencies. But I also believe many children and adults are on their phones too much causing them to lack interest in outdoor activities. The internet has revolutionized in many ways, but some cases it is good and in some cases bad. It is good because it can give students apps for learning, but the lack of students and people, in general, don't have interests in other things which is bad for health. Like looking at the blue screen (any electric screen).
