US officials defend shooting of mentally ill air passenger

By all accounts, Rigoberto Alpizar was frantic as he darted off a plane at Miami International Airport, bumping past passengers and yelling that he needed to get off the aircraft.

However, passengers say they never heard him say anything about a bomb. Federal officials say he shouted that he had a bomb in his bag, and ignored instructions to get down. When he reached for the bag, the marshals opened fire, killing him.
