Schools in the United States started integrating in the 1950's as a direct result of the Brown v Board of Education Supreme Court ruling.
Miranda v. Arizona has a very significant impact today. This case ruled that any arrested person must be read his/her Miranda Rights (You have the right to remain silent. Anything you say can and will be used against you in a court of law. Etc.). This is due to the fact that many people self-incriminated themselves because they were unaware of their rights. This lead to innocent people being accused of crimes.
Hope this helps!
