9. President Ulysses S. Grant was arrested for speeding on a horse. Ulysses S. Grant, the 18th president of the United States, didn't always follow the law, even while he was in office. The skilled equestrian enjoyed traveling at high speeds, which was illegal. When Grant was caught going at a so-called "furious pace," he was given a firm warning by police officer William H. West. Although Grant apologized, he was caught speeding the very next day by the same officer. As a result, he was arrested and taken to the police station, where he was booked and fined for his offense.
