DEKALB COUNTY, Ga. -- On the second day of testimony in the immunity hearing for former DeKalb County Police Officer Robert Olsen, prosecutors called DeKalb County police instructor Greg Webb.
Olsen is accused of killing an unarmed, naked Air Force veteran in March 2015 while responding to an apartment complex.
Olsen previously testified he had encountered Anthony Hill an Air Force veteran who had served in Afghanistan. Hill was naked and unarmed. Olsen said Hill "attacked" him, and, supposedly fearing for his life, Olsen shot and killed Hill.
Hill's family said he was dealing with post-traumatic stress disorder.

Webb said that he would not have approached Anthony Hill as Olsen did.
"If it's not warranted for me to approach them, then I would not approach them for fear that it might set them off," Webb said.
He says all officers are trained to de-escalate situations they are faced with.
The prosecutor asked Webb if he would point a gun at someone to de-escalate a situation.
"No," Webb said.
"Would you shoot that person twice?" the prosecutor asked.
"Based upon those facts and circumstances, I would not," Webb said.

"Is a naked running man a physical threat to you at 150 feet?" the prosecutor asked.
"Not based on those facts and circumstances," Webb said.
He said that officers receive non-lethal training which would have been more appropriate for Olsen to use on Hill. Webb says that were he in a similar situation, he would have called for backup and stayed in his car.
The defense attorney asked Webb if it is police department policy that officers have to use all forms of non-lethal force before they move on to using deadly force.
Webb replied that it is not department policy.
The defense attorney said that sometimes officers only have five seconds to make a decision.
"You don't go through a checklist, do you?" the defense attorney asked.
"You do, actually," Webb said. "You go through your training."
The defense also called Valdosta State University professor Dr. Darrell Ross as an expert witness on use-of-force.
Ross said that any officer with "that type of information," referring to the knowledge that Olsen had when arriving on the scene, would be on "high alert." He says he feels Olsen acted appropriately when he shot and killed Hill.
"We know that this type of situation can bring serious bodily injury or harm to an officer," Ross said. "This kind of individual is known to be extremely strong, impervious to pain."
Ross said that any of the non-lethal options -- Taser, baton, spray -- would have been inappropriate.
"This was a deadly-force type of situation," he said.
After Ross stepped down, both the prosecution and defense presented their closing arguments.
