If you saw a fat man in a sleigh distributing presents this week, he was in violation of several government regulations. The Federal Aviation Administration has complaints about his secret flight path. The Wisconsin Department of Natural Resources might shoot his unauthorized reindeer the way they shot a baby deer named Giggles at an animal shelter this year. His bag of gifts definitely violates numerous charity tax rules. In real life, writes John Stossel, government barely lets people give each other rides in cars. Sooner or later, if we restrain the regulators, the market might even produce flying sleighs.
