Southern police district commander Superintendent Bob Burns said he did not agree with any suggestion from the Alexandra community Dairne Cassidy was a scapegoat for other police.
"She was certainly not a scapegoat."
Police acknowledged Cassidy was under some pressure at the time of the incident, but her initial decision to withhold information was an individual decision, he said.
"The investigation found that no-one else was part of that decision-making."
He said a review by police at national headquarters was looking at how police could have identified the cover-up earlier and how it could have handled concerns raised by members of the community in a better way.
Asked if he had faith in the integrity of the other officers who worked at the station at the time of Mr Ford's crash, he said extensive investigations and reviews had not uncovered any integrity or criminal issues with any other staff at the Alexandra station.
"There is certainly procedural stuff that is currently being looked at, and we have already identified procedural and policy issues that have already been changed."
He said the investigation into Cassidy's allegations of bullying by a senior officer was carried out by an experienced detective inspector from outside the district.
The investigation found no evidence of bullying.
