[Edit - It has been later clarified that the pornography in question was underage, so the below post no longer applies to this case.]

Florida still seems to think that pornography is illegal, just yesterday arresting the author of the "how to be a pedophile book" for writing it. Not because it might incite people to harm children, but because the text within was "obscene."

Technically, porn is still illegal according to federal law and the laws of many states, especially Florida. However, it's nearly certain that the Supreme Court would find that private possession of porn is constitutionally protected, which is one of the reasons why you almost never see a prosecution for general (18+) porn.
