The Bill of Rights, consisting of the first 10 amendments to the U.S. Constitution, defined the basic rights afforded to all American citizens, as well as some limitations of government. For example, it guarantees people's freedom of religion, press, and expression, it protects people's right to enjoy a speedy and public trial by an impartial jury in criminal prosecutions, people's right to be free from unreasonable government intrusion in their homes through the requirement of a warrant, and it also establishes the right to have reserved powers, that is to say, that the powers not delegated to the United States by the Constitution, nor prohibited by it to the states, are reserved to the states respectively, or to the people.
