The Stolen Valor Act, at 18 U.S.C. 704, makes it a federal crime to lie about having certain military honors.
The Ninth Circuit, in an opinion that can almost never be quoted enough, held that the Stolen Valor Act is unconstitutional. Judge Kozinksi writes,
Saints may always tell the truth, but for mortals living means lying. We lie to protect our privacy (“No, I don’t live around here”); to avoid hurt feelings (“Friday is my study night”); to make others feel better (“Gee you’ve gotten skinny”); to avoid recriminations (“I only lost $10 at poker”); to prevent grief (“The doc says you’re getting better”); to maintain domestic tranquility (“She’s just a friend”); to avoid social stigma (“I just haven’t met the right woman”); for career advancement (“I’m sooo lucky to have a smart boss like you”); to avoid being lonely (“I love opera”); to eliminate a rival (“He has a boyfriend”); to achieve an objective (“But I love you so much”); to defeat an objective (“I’m allergic to latex”); to make an exit (“It’s not you, it’s me”); to delay the inevitable (“The check is in the mail”); to communicate displeasure (“There’s nothing wrong”); to get someone off your back (“I’ll call you about lunch”); to escape a nudnik (“My mother’s on the other line”); to namedrop (“We go way back”); to set up a surprise party (“I need help moving the piano”); to buy time (“I’m on my way”); to keep up appearances (“We’re not talking divorce”); to avoid taking out the trash (“My back hurts”); to duck an obligation (“I’ve got a headache”); to maintain a public image (“I go to church every Sunday”); to make a point (“Ich bin ein Berliner”); to save face (“I had too much to drink”); to humor (“Correct as usual, King Friday”); to avoid embarrassment (“That wasn’t me”); to curry favor (“I’ve read all your books”); to get a clerkship (“You’re the greatest living jurist”); to save a dollar (“I gave at the office”); or to maintain innocence (“There are eight tiny reindeer on the rooftop”).
