San Francisco's Millennium Tower slow to fix windows

Last spring, a window at San Francisco’s Millennium Tower blew out of its frame during a wind storm raising questions and concerns about safety of the city’s high rise buildings in bad weather. The incident, and half a dozen others, triggered calls for inspections, and changes. But as NBC Bay Area’s Investigative Reporter Jaxon Van Derbeken explains, not much appears to have changed at the tower, one year later.
