PASCO COUNTY, Fla. — Closing arguments will begin Friday morning in the movie theater shooting trial of Curtis Reeves, who spent more than five hours on the stand Thursday.

Reeves, 79, is facing charges of second-degree murder and aggravated battery and could spend the rest of his life in jail if found guilty in the January 2014 shooting of Oulson, who was 43.

Reeves' attorneys have claimed he acted in self-defense when he shot Oulson after the two argued over Oulson’s cell phone use before a movie started.

Attorneys from both sides Thursday made their cases for answering the central question: Did Reeves shoot Oulson out of fear, or blind rage?

On the stand, Reeves told jurors he felt he had no choice when he shot Oulson. He said after he reported Oulson for using his cell phone during previews, the younger man's anger was "explosive” and that Oulson was “completely out of control.”

"When he stood up, I'm sitting down in a completely defenseless position,” Reeves said. “I'm looking up at this guy, and he looked like a monster standing there."

The defense tried to show that Reeves used threat assessment skills from his decades in law enforcement to determine Oulson was a real threat.

The prosecution pointed out academy training is more than twice as long for Tampa officers today.

Assistant State Attorney Scott Rosenwasser said there were inconsistencies between Reeves' testimony and previous statements, as well as with surveillance footage.

For instance, Reeves didn't tell the first detective he spoke with that he thought Oulson may have thrown his phone at him.

When asked why, Reeves said he hadn't seen the video at that time.

"So, you're not telling us that you're tailoring your testimony to what you witnessed in the video, are you?" he was asked.

“I think the video is supporting my position,” Reeves said.

"OK. Even though it's been shown that the reflection was clearly your shoe?" Rosenwasser asked.

Reeves answered, "I don't think in every instance it's been shown that way."

The prosecution also stressed that Reeves initiated each contact with Oulson.

Reeves told his attorney he hadn't expected a conflict that day.

"I didn't want to shoot anybody,” he said. “I came to the theater with my family to enjoy a movie, not to be attacked by some guy that's out of control."

Rosenwasser also asked Reeves if he intentionally shot Oulson. Reeves says yes and agreed it wasn't accidental.

"Did you kill him out of rage?" Rosenwasser asked.

"No," says Reeves.

"Did you kill him out of blind fury?"

"No, sir. I killed him out of fear."

"You didn't just snap and kill him?"

"No."
