Shocking video shows a helicopter opening fire with an extraordinary display of fireworks at a Lamborghini. It was apparently shot on a dry lake bed in California. Now, the YouTuber believed to be behind the outlandish stunt is in hot water because, authorities say, he didn’t have a permit. YouTuber Alex Choi is being charged with "causing the placement of an explosive or incendiary device on an aircraft," which is a federal offense.
