Huge Security Operation Under Way as Britain Prepares For Royal Wedding

The big day is nearly here for Britain's Prince Harry and Meghan Markle as the couple are to wed Saturday in the town of Windsor, just outside London. The former American actress confirmed this week that her father will not attend the ceremony because of ill health. Huge crowds are expected as well-wishers try to catch a glimpse of the royal couple and, as Henry Ridgwell reports, from the security operation, to the catering, to the flowers, the day marks the culmination of months of preparation.
