What does the Bill of Rights protect?

What does this answer mean?

The Bill of Rights protects the basic rights of Americans and of people living in the United States. It is the name for the first ten amendments to the Constitution.

When the states approved the Constitution, several of them asked for clauses that would clearly limit the new national government's powers. In 1789, the First Congress proposed 12 amendments, and ten of them were ratified on December 15, 1791. Those ten are the Bill of Rights.

They protect many rights you may know. The First Amendment protects freedom of religion, speech, and the press, the right to gather peacefully, and the right to petition the government. Other amendments protect against unreasonable searches and protect people accused of crimes, including the right to a speedy and public trial and the right to a lawyer.

Notice the second accepted answer: these protections cover people living in the United States, not only citizens. Either answer is correct at the interview.
