15-year-old Tennessee football star

Two girls owe their lives to the actions of a 15-year-old Tennessee football star, who shielded them when bullets began flying last Thursday evening in Knoxville. 

This weekend, President Barack Obama took to Twitter to recognize the heroism of Zaevion Dobson, who was killed in last week's random gang-related shooting. "Zaevion Dobson died saving...friends from getting shot. He was a hero at 15. What's our excuse for not acting?" he wrote. 

This is bravery, would you die for your neighbor?
