Pistorius apologized to the family his late girlfriend, Reeva Steenkamp, who he shot and killed last year at his home in South Africa. The Olympian claims he thought she was an intruder, but the prosecution has tried to paint him as a hothead who killed her during an argument.

In court, he said, “I was simply trying to protect Reeva. I can promise that when she went to bed that night she felt loved.”

Pistorius testified that he is scared to sleep because of “terrible “nightmares. “I wake up and I smell – I can smell blood,” he said.

He also said he never wanted to handle a firearm again. Fox News producer Paul Tilsley, who was in the courtroom, reported that when the cameras were turned off Pistorius was in a highly emotional state and had to be comforted by his family before leaving.

On Happening Now, criminal defense attorney Heather Hansen and defense attorney Jonna Spilbor provided legal analysis on the latest developments.

Hansen said that Pistorius’ testimony today was to garner sympathy, but ultimately it’s irrelevant to establishing the reason why he shot Steenkamp.
