Human rights refer to inherent rights, while civil liberties are legal rights and freedoms protected by a country's constitution or basic laws. The war on terror has increased defense measures that affect civil society through more surveillance and less privacy. The USA Patriot Act expanded government powers to investigate terrorism but reduced some civil liberties; Title II allowed for increased surveillance that was controversial due to privacy concerns. Scholars Cole and Dempsey argue that antiterrorism laws can undermine civil liberties if not balanced with oversight.
