"I think the media wants to know," he said.
He said the office was still reviewing the incident internally.
"We may tweak some policies. Or maybe we won't tweak them," he said.
Neither the sheriff, nor the prosecutor, nor the lead detective on the case could say precisely how many officers were on scene when the shooting began.
Lt. Greg Young, the detective in charge of the investigation, would only say that there were several.
Police distributed a timeline at the beginning of the press conference but brought no notes or diagrams to the meeting, relying on their memories to describe to the public the details of the tragedy.
Good's mother Patricia Harrison continually interrupted the sheriff and officials. She demanded "justice" for her son.
When Rutherford described police shooting her son, Good's mother wailed. She repeatedly interrupted the press conference, prompting both Rutherford and Plants to address her directly.
At one point she complained that Charleston Mayor Danny Jones had compared her son to a terrorist on television.
"We're not here for Danny Jones," Rutherford said. "We're here for a news conference."
"Not only did they not break any laws in a very dangerous situation that could have turned out to be a lot worse," Plants said.
Harrison interrupted him, saying how could it get worse since her son and a police officer were dead.
"They did it to protect me and my family who drive around this area," Plants said.
He said police deserve praise for protecting the public the way they did that night.
"You praise them," Harrison said. "Because I won't."
