Does the Constitution Protect Lying?

Of course it does. That is what I thought before I read this article, but now I am not so certain. At issue is a law that punishes people for falsely claiming to have been awarded an armed forces decoration or medal. Proponents of the law argue that false statements of fact are not protected by Free Speech. Opponents argue that virtually all speech must be protected. With two contrasting court opinions, it looks like this case is destined for the Supreme Court.
