What happens when the Secret Service uses a NSL on you
First Amendment to the US Constitution:    Congress shall make no law respecting an establishment of religion, or
    prohibiting the free exercise thereof; or abridging the freedom of speech, 
    or of the press; or the right of the people peaceably to assemble, and to 
    petition the Government for a redress of grievances.

Can someone please show me the asterisk that says "unless done to protect national security"?
