A former New Orleans police officer has testified at his retrial that he thought he saw a gun in the hand of the man he shot and fatally wounded outside a strip mall in Hurricane Katrina's aftermath.
David Warren's testimony Monday marks the second time he has tried to explain to a jury why he fired a shot at 31-year-old Henry Glover less than a week after the storm's landfall.
Warren says he feared for his life when he shot Glover, but prosecutors say Glover wasn't armed and didn't pose a threat.
Warren was convicted of manslaughter in 2010. But an appeals court overturned his convictions last year, ruling he should have been tried separately from four other former officers charged with participating in a cover-up of Glover's death.
