What is the relationship between "fair" and "law"? Does one influence the other? Does public opinion play a role in how the courts (especially the Supreme Court of the U.S. ) interpret the law? Does this information help you predict how the law may or may not change?
Law are the legal rules we follow and fair is usually the moral rules that we follow. Sometimes the law isn't fair because the basis of the law isn't necessarily morality but rather a technical set of laws that society has formed that they can bear to abide by.
