Gabby Giffords remembers facing her assailant at his sentencing.
"Beady eyes," she said of Jared Loughner, who shot the former Arizona congresswoman in the head with a 9mm Glock pistol. Six people died and 13 were injured that day when the deranged gunman opened fire in front of a Tucson supermarket.
At the sentencing last November, Giffords sat stoically - staring Loughner down - as her husband, Mark Kelly, spoke to the court.
"Well, yes, he had some interesting expressions on his face," said Kelly. "And she did not look away."
"Beady eyes," Giffords repeated.
In an exclusive, wide-ranging interview with CNN, Giffords and Kelly understand they are now in the center of the heated debate over gun control and background checks, while still struggling to rebuild their lives after that day in January 2011, when their lives changed forever.
