When you think of "federal crime," you probably think of big-ticket offenses like mail fraud, identity theft, and tax evasion. But our criminal code is also full of, shall we say, lesser offenses. For example, according to the Crime a Day Twitter feed, "18 USC §1854 makes it a federal crime to cut, chip, or chop a government-owned tree to get turpentine out of it." 7 USC §8313 "makes it a federal crime to bring an imported camel's blanket into the United States without the permission of the port inspector." And 8 USC §1865 "makes it a federal crime to roller skate in Alaska's Sitka National Historical Park."
