Weinstein, taken hostage by al Qaeda in 2011, devoted life to helping others

Warren Weinstein is one of the two hostages who were killed in a CIA drone strike in January. The counterterrorism operations also killed two additional Americans who joined al Qaeda. It is believed they were using Weinstein and an Italian hostage as shields. Wyatt Andrews reports on the story from outside the Weinstein family home in Rockville, Maryland.
