The preamble to the U.S constitution contains a quote - “securing the blessings of liberty”, which means that the Constitution safeguards the liberty of American citizens at all points of time. The “blessings of liberty” also means that the freedom of speech, the liberty to do what one desires, without any fear or prejudice is also applicable. Of course these civil liberties are granted with limitation. For example, the freedom of speech cannot mean one is free to make slanderous or racial comments.
