The Legislature of Louisiana does hereby take cognizance of the fact that much of the world is in a state of political unrest; that foreign agents and others who seek the overthrow or destruction of the government of the United States are known to be working in our country, and that such a situation presents a clear and present danger; and it is hereby declared to be public policy that subversive activities by any public employee, or by any student in a public educational institution in this state, should not be permitted, and this act is enacted to prohibit such subversive activities.
