Reeves was charged with aggravated battery charge in that injury.
The bond hearing began Wednesday. Judge Pat Siracusa heard from Reeves' family, friends and former colleagues who testified he didn't have any anger problems and would not be a flight risk.
Reeves told the detective that Oulson hit him in the face and that his glasses became crooked. Reeves said to the deputy that he might have been hit with a cellphone, but prosecutors disputed that suggestion.
"It scared the hell out of me," said Reeves, adding that had he been younger, he would have "wrassled" Oulson to the ground. "The guy was very aggressive."
Reeves' wife told a detective she didn't see Oulson strike her husband, but he told her he had been hit in the moments after the shooting.
Vivian Reeves also told detectives that Oulson used expletives, but didn't make any threats. She cried during the interview and said she didn't know why her husband fired the single shot.
"He was in law enforcement 20 years, and he never shot anybody," she said. "He's never threatened anybody with a gun."
In an interview this week on ABC's "The View," Nicole Oulson said her husband was texting with their daughter's baby sitter.
Reeves "had confronted my husband several times, which my husband ignored and ignored and ignored. And it just got to a point where my husband spoke up," she said.
